From: Jonathan Marten <jjm <at> keelhaul.me.uk> To: bug-gnu-emacs <at> gnu.org, bugs <at> gnus.org Subject: 24.5; nnimap: anonymous login to IMAP server not working Date: Sun, 16 Oct 2016 06:06:19 +0100
Gnus (gnus-version = "Gnus v5.13") configured for anonymous IMAP login
does not log in to the IMAP server. Setting in .gnus:
(setq gnus-secondary-select-methods
'((nnfolder "")
(nnimap "imapserv"
(nnimap-authenticator anonymous)
(nnimap-stream network))))
and starting Gnus produces the echo area messages:
Reading /home/jjm/.newsrc.eld...
Checking new news...
Reading active file via nnfolder...
Opening nnfolder server...done
nnfolder: Reading incoming mail (no new mail)...done
Reading active file via nnfolder...done
Opening connection to imapserv...
Reading active file via nndraft...done
Checking new news...done
No news is good news
with all of the groups on that server showing "*" for the message counts.
Entering one of those groups produces the message "Couldn't open server". In
the server buffer the server is shown as:
{nnimap:imapnews} (denied)
Observing the IMAP network connection with wireshark shows that the CAPABILITY
request is sent and returned correctly, but no further IMAP activity takes
place after that (in particular, no LOGIN is sent).
Stepping through nnimap-login in nnimap.el shows that the parameters passed to
it are user="anonymous", password=(email address). The problem seems to be
that nnimap-authenticator=anonymous is not handled by any of the conditions in
this function, so no login is sent. Applying the patch:

handles the anonymous login case (in the same way as plain login) and
correctly logs in to the IMAP server.
