Gnus 5.x Frequently Asked Questions
This is the Gnus Frequently Asked Questions list.
Gnus is a Usenet Newsreader and Electronic Mail User Agent implemented
as a part of Emacs. It's been around in some form for over 6 years
now, and has been distributed as a standard part of Emacs for much of
that time. Gnus 5 is the latest (and greatest) incarnation. The
original version was called GNUS, and was written by Masanobu UMEDA.
When autumn crept up in '94, Lars Magne Ingebrigtsen grew bored and
decided to rewrite Gnus.
Its biggest strength is the fact that it is extremely customizable. It
is somewhat intimidating at first glance, but most of the complexity
can be ignored until you're ready to take advantage of it. If you
receive a reasonable volume of e-mail (you're on various mailing
lists), or you would like to read high-volume mailing lists but cannot
keep up with them, then you definitely want to investigate Gnus for

Subject: Q1.1 What is the latest version of Gnus?
Gnus 5.8 has been released!
As of this posting, the latest Gnus version is 5.8.2. Gnus 5.8 should
still be considered beta at this time, but is in feature-freeze and
bugs are being actively fixed. Download your copy today.
A warning for upgrading users, however: Due to the many changes in 5.8
(especially mail sources and MIME) your dotfiles may not be
forward-compatible. Please read the documentation before you upgrade.
Gnus 5.0.13 is included in the official distribution of Emacs
19.30/19.31 and has a version number of 5.1. Do not attempt to use
this release of Gnus with other Emacsen, as the necessary required
support has been stripped out of it. Gnus 5.2.38 aka Gnus 5.3 is
included in Emacs 19.32 and all later versions of Emacs 19.x. Gnus 5.5
is shipped with Emacs 20.x.
Gnus 5.2.25 is included standard with XEmacs 19.14, Gnus 5.4.37 is
included with XEmacs 19.15p7, Gnus 5.5 is included with XEmacs 20.4,
and Gnus 5.6.45 is packaged alongside XEmacs 21.1.7.
Subject: Q1.2 Where do I get Gnus?
The latest version is available via HTTP at
<URL:http://www.gnus.org/gnus.tar.gz> or anonymous FTP at
Patches are available at <URL:http://www.gnus.org/patches/>.
You can also fetch it from the North American mirrors:
>, or <URL:ftp://aphrodite.nectar.cs.cmu.edu/pub/ding-gnus/>.
The last site should only be used as a last resort.
Or, get it from a mirror in South America:
<URL:ftp://ftp.unicamp.br/pub/news.software/gnus/> or Australia:
Subject: Q1.3 Which version of Emacs do I need?
Gnus 5.8.x requires an emacs version that is greater than or equal to
Emacs 20.x or XEmacs 20.x.
Prior to Gnus 5.2, at least GNU Emacs 19.28, or XEmacs 19.12 was
recommended. GNU Emacs 19.25 has been reported to work under certain
circumstances, but it doesn't officially work on it. 19.27 has also
been reported to work.
Because of Gnus 5.2's use of Common Lisp features present only in
late-model emacsen, it will only work with Emacs 19.30 or later, and
XEmacs 19.13 or later.
Emacs 20.2 has many show-stopping bugs. If you are using Emacs 20.2,
upgrade to 20.3.
Gnus 5.4 requires emacsen at least as recent as Emacs 19.33 or XEmacs
Gnus has been reported to work under VMS, OS/2, and Microsoft Windows
NT 3.51, as well as Unix.

Subject: Q1.6 How do I unsubscribe from the Mailing List?
Send an e-mail message to <URL:mailto:email@example.com> with the
magic word unsubscribe somewhere in it, and you will be removed.
Subject: Q1.7 How do I run Gnus on both Emacs and XEmacs?
You don't. Gnus is distributed with both emacsen, use the version of
Gnus that comes with your emacs.
Subject: Q1.8 What resources are available?
There is the newsgroup Gnu.emacs.gnus. Discussion of Gnus 5.x is now
taking place there. There is also a mailing list, send mail to
firstname.lastname@example.org with the magic word subscribe somewhere in it.
NOTE: the traffic on this list is heavy so you may not want to be on
it (unless you use Gnus as your mailer reader, that is). The mailing
list is mainly for developers and testers.

Subject: Q1.10 Mailcrypt 3.4 doesn't work
You are attempting to use the mailcrypt 3.4 distribution with Gnus
5.3. Mailcrypt 3.4 needs some minor patches to work with Gnus 5.,

Alternately, you can use gnus-setup.el to activate tm, bbdb,
supercite, and other packages. See Question #2.12 for details.
If you are using an XEmacs version of 19.15 or newer, you do not need
tm as it is now included standard with XEmacs.

Subject: Q1.12 How do I make Gnus start faster?
Make sure you kill your unsubscribed groups. This will make Gnus start
much faster, and keep your .newsrc file sizes down to boot.

I would rather write: 'ask-server [for the value of
gnus-check-new-newsgroups] instead of nil. It is more useful to most
people, and does not increase the load time too much.
Subject: Q1.13 I've upgraded to 5.2 (or greater) and my hooks no longer work
Gnus now uses a combined mode for editing mail and news posts called
message-mode. All your hooks must change to reflect this. You can
either use gnus-setup.el provided with Gnus 5.2 (please see Q2.12 for
details), or you can make the changes by hand.
In particular, mail-mode, news-reply-mode, and news-mode have all been
replaced with message-mode.
Subject: Q1.14 How do I specify the NNTP server?
There are a variety of ways, all documented in the Gnus user's manual.
1. (setq gnus-select-method '(nntp "news.somewhere.edu"))
2. (setq gnus-select-method '(nnspool ""))
3. If gnus-select-method is not set, Gnus will take a look at the
NNTPSERVER environment variable. If that variable isn't set, Gnus
will see whether gnus-nntpserver-file (/etc/nntpserver by default)
has any opinions on the matter. If that fails as well, Gnus will
try to use the machine that is running Emacs as an NNTP server.
4. If gnus-nntp-server is set, this variable will override
gnus-select-method. You should therefore set gnus-nntp-server to
nil, which is what it is by default.
5. You can also make Gnus prompt you interactively for the name of an
NNTP server. If you give a non-numerical prefix to gnus (i.e., C-u
M-x gnus), Gnus will let you choose between the servers in the
gnus-secondary-servers list (if any).
Subject: Q1.15 What is the difference between persistent and unexpirable
Lars Magne Ingebrigtsen <firstname.lastname@example.org> writes: The terms are not
synonymous, they are orthogonal.
If you tap * on an article, you have made it persistent. Nothing you
ever do, except using the M-* command, will remove it from the cache
where it's stored.
If you mark an article with the E mark, (ie., made it expirable), it
will be deleted by the mail backend when it reaches a certain age. The
persistent copy of the message will not be touched.
The two terms are not related.
Subject: Q1.16 Does Gnus have MIME support?
Gnus 5.8.x has native fully-integrated MIME support.
If you are using an earlier version of Gnus, there are some other
packages that you can use with Gnus. A link to Tools for MIME can be
found in the other packages question.
Note: TM will not work in any version of Gnus that has native MIME
2. Customizing Gnus
Subject: Q2.2 How do I quote messages?
I see lots of messages with quoted material in them. I am wondering
how to have Gnus do it for me.
This is Gnus, so there are a number of ways of doing this. You can use
the built-in commands to do this. There are the ``F'' and ``R'' keys
from the summary buffer which automatically include the article being
responded to. These commands are also selectable as Followup and Yank
and Reply and Yank in the Post menu.
C-c C-y grabs the previous message and prefixes each line with
`message-indentation-spaces' spaces or `message-yank-prefix' if that
is non-nil, unless you have set your own `message-cite-function',
which will be called to do the job.
You might also consider the Supercite package, which allows for pretty
arbitrarily complex quoting styles. Some people love it, some people
If you decide to use Supercite, you need to modify more than just
`mail-citation-hook'. You need something similar to the following:
(autoload 'sc-cite-original "supercite" "Supercite 3.1" t)
(setq message-cite-function 'sc-cite-original)

Subject: Q2.9 How can I make favorite authors be highlighted in the Summary
Per Abrahamsen <email@example.com> writes:
Just increase their score, and they will be highlighted.
You can increase the score of all articles written by Larry Wall in
comp.lang.perl by entering the group, find an article written by Larry
Wall, and type I A (Increase Author) or even better I a s p (Increase
author by substring permanently). You will be prompted with the
content of the From header for the current article, so you can edit
trim string down to just Larry Wall if you want.

I just stumbled into a nasty gotcha, a conflict between Gnus (probably
any version) and any on-the-fly file compression hooks. This morning,
the code that pulls the system mailbox into a local Incoming file
created a file called Incominga003.Z. The problem should be apparent:
the .Z extension gets the file flagged as compressed, so the
compression code tries to decompress it; since it is not compressed,

Gnus attempts to follow mail and news RFCs by adding a Sender header
when it detects that you are sending a message with a From address
that is different from what it has guessed your local email address to
There are two situations in which this guess will be incorrect.
1. (user-login-name)@(system-name) should be a valid email address
for you, but Gnus is creating an invalid Sender field.
In this case, your system is most likely misconfigured. You should
not change your Gnus configuration. Instead, track down the
configuration problem and fix it.
2. Due to your mail-reading setup, (user-login-name)@(system-name)
does not produce a value that is meaningful in any way. This is
the case for many windows users and users with NAT-based home
networks, for example.
If this is so, then you should override the functions
(user-login-name) and (system-name) in your ~/.emacs file.
However, if you are trying to change your Sender header just so that
you will not have a correct email address anywhere in your headers,
you should think again. There is no good reason to send news or mail
with incorrect and unreachable headers. Among other things, this is a
rude and selfish way to attempt to reduce one's flow of spam. Please,

Subject: Q2.22 Base64 decoding and encoding appears to be horribly slow in
Pterodactyl Gnus. What can I do about it?
Hrvoje Niksic <firstname.lastname@example.org> answers:
Since the current Emacsen do not support base64 in native "C" code,
Pterodactyl Gnus implements base64 decoding and encoding in Lisp. This
is inherently slow because base64 operations consists of examining
each character in turn, and doing arithmetics on them -- repeated for
thousands of characters. However, Gnus allows you to use an external
base64 decoder, if you have it.
For example, if you have Nathaniel Borenstein's "metamail" package,
here is how to tell Gnus to use its `mimencode' program to decode
(setq base64-decoder-program "mimencode"
(setq base64-encoder-program "mimencode")
Note that, beginning with XEmacs 21.2 and GNU Emacs 20.4, the popular
Emacsen will support base64 natively, which will be faster than even
the external encoders, making above hack obsolete.
Also note that uudecoding, as performed by mm-uu, is also done in Lisp
by default. You can make Gnus use the external Unix decoder like this:
(setq mm-uu-decode-function 'uudecode-decode-region-external)

1. Use mm-inline-override-types.

Subject: Q3.8 Evil nntp
Yair Friedman <email@example.com> writes:
Does anyone has experience with setting nntp-nov-is-evil to t? What
exactly will I gain or lose by setting this variable?
Setting this variable only makes sense if netnews is set up on your
system to not provide XREF (cross reference information) in the
overview files Gnus reads to build group summaries.
A quick test to see if you need to use it is this (substitute your
nntp server, and use the last number returned on the 211 line as the
parameter to XOVER):
(Example courtesy of Christopher Davis <firstname.lastname@example.org>).
$ telnet news.somewhere.com nntp
You should see something like the following (on INN systems anyway):
215 Order of fields in overview database.
If the Xref:full is missing, ask your news administrator to add it in.
Assuming you have a broken newsfeed, you gain by setting
nntp-nov-is-evil the ability for Gnus to mark all crossposted articles
as read the first time you see them. Otherwise, every crossposted
article is spam, and you see it over and over again if you also read
the other groups it is crossposted to.
You lose the ability to have Gnus fill in old headers to flesh
partially read threads with old articles. This may not matter a whole
lot if expiration times are short. Building group summaries is also
somewhat slower, though if your network connection to the news server
is decent this isn't a huge loss.
Subject: Q3.9 Posting to foreign servers.
Reading news off of multiple news servers is great, but posting to

This will be changed in the near future so that postings will go to
the server that the group is being read from when no prefix is given.
Steinar Bang <email@example.com> suggests a workaround until then:
Put the following in ~/.emacs or ~/.gnus:
;; Hack for posting on foreign servers
(local-set-key "\C-c\C-c" 'message-send-and-exit-with-prefix)))
(defun message-send-and-exit-with-prefix ()

of the default NNTP server"
Subject: Q3.10 Gnus hangs when I try to send a post to my news server. What is
wrong and what can I do to fix it?
Due to a bug in early versions of Gnus, it was sometimes unable to
post consistently to certain servers, notably Typhoon. Sometimes it
would fail on the first attempt but succeed if one tried to post the
same article again.
If you experience this problem, you should upgrade to a version of
Gnus with a version number of 5.6 or greater. The most recent non-beta
release is recommended.
4. Reading Mail
Subject: Q4.1 What does the message Buffer has changed on disk mean in a mail
Your filter program should not deliver mail directly to your folders,

explicitly marking an article as un-expirable - that is mark it as

the `E' mark by setting some other mark. It's not necessary to tick

with such a Gnus and want to remove mail groups, you basically have to

exclude these groups, and probably remove the nnml directories that
contained these groups as well. Then start Gnus back up again.

Richard Pieri <firstname.lastname@example.org> says:
It does not require an external program, which is important on certain
versions of Emacs running on certain operating systems that cannot

pass password information to an external process insecurely.

Subject: Q4.17 My splitting rules seem to miss a few messages. Why?
If Gnus tried to match some of the regexps used in splitting against
extremely long header lines, the match attempt would take far too long
to be tolerable.
To deal with this, Gnus excludes long header lines from the function
that does the splitting. If a mail message has, for example, a To:
header longer than 1024 characters, that line will not be considered
for splitting purposes.
Very recent versions of Gnus (pgnus, thus all official versions >=
5.8) deal with this a bit better. In those versions, the long lines
are truncated instead of excluded, and there is a variable,
nnmail-split-header-length-limit, to control the threshold for
Subject: Q4.18 What is the difference between total-expire and auto-expire?
When an article is read (the word `read' here being a verb, not a noun
referring to the mark), Gnus also marks it as expirable (`E'). When
the expiry process occurs, it explicitly uses the articles marked with
`E' as the set of articles eligible for expiration.
No `E' marks are used or relevant at all. When the expiry process
occurs, articles marked as read are eligible for expiration. Note that
this means articles that are not unmarked and are not marked with
either `!' or `?' as both of those marks are just special ways of
The real difference:
The benefit of auto-expire is that in really huge groups (several
thousand messages) or groups with really old ticked of dormant
messages, the expiry process will be much faster. This is due to the
fact that Gnus has an explicit list of eligible articles, instead of
having to rebuild such a list each time expiry is invoked.
The benefit of total-expire is that it is simpler. There is no such
thing as a special mark for expirable messages. All articles that are
read and not marked otherwise will be expired once they are old
