Hi,
I would like to move from a nnmaildir + OfflineIMAP configuration to
something which:
1. scales better for large number of messages than nnmaildir and
2. does not use OfflineIMAP (Python 2 based and sometimes slow).
I understand that some Gnus users use a local IMAP server with dovecot
and the nnimap backend.
I found these interesting instructions here:
https://ericabrahamsen.net/tech/2014/oct/gnus-dovecot-lucene.html
but I am having trouble making them work.
I had to change some of the mbsync settings since they are now
deprecated (the post is 6 years old), but still no success (I have
failed authentications for mbsync while the same config works if I don't
use dovecot).
I would like to know if somebody could share their dovecot and mbsync
configurations for a more recent setup. I am running Debian stable, but
I guess that I can translate distribution specific things if needed.
Thanks for your help.

I'm still using this setup! You didn't say what was going wrong, but
here's a sample config block for one of my IMAP accounts:
IMAPAccount ea
Host mail.ericabrahamsen.net
User eric@ericabrahamsen.net
PassCmd "/usr/bin/pass email/ea"
SSLType STARTTLS
Port 143
IMAPStore ea-ro
Account ea
IMAPAccount local-ea-dovecot
SSLType None
Host localhost
User eric-local@ericabrahamsen.net
Pass <boguspassword>
AuthMechs LOGIN
IMAPStore ea-daemon-local
Account local-ea-dovecot
Channel ea
Master :ea-ro:
Slave :ea-daemon-local:

Thanks for your answer!
With respect to the 2014 post, for the mbsync part, I had to change
,----
| UseIMAPS no
| UseTLSV1 no
`----
to this
,----
| SSLType IMAPS
| SSLVersions TLSv1.2
`----
and also add the port as you have in the example you just gave.
And now I also see that for the local dovecot, you have
,----
| AuthMechs LOGIN
`----
which was not the case in the blog post. This may be why I was getting
an authentication failure.
I will try again with this updated configuration (my next scheduled
session to play with this is next week-end!).
Do you remember having also updated dovecot.conf or other things?
Thanks!

Looks like it's time to update the blog post...

I tried to keep dovecot as bog-standard as possible. The only changes I
made to dovecot.conf were to set the location of the password file and
where to store mail, and most importantly to turn on full-text search.
Then there was the passwd file itself.
I think that was it!
Eric

Here is my setup using offlineimap to sync mail with gmail and dovecot to speak imap with gnus.

Hi,
Thanks to Eric Abrahamsen and Jeffrey DeLeo for their help. I finally
managed configuring dovecot + mbsync + gnus to my liking.
Actually, the original post from Eric just needed a couple of tweaks to
work. As pointed out before, in the mbsync config, I had to change this
,----
| UseIMAPS no
| UseTLSV1 no
`----
to this
,----
| SSLType IMAPS
| SSLVersions TLSv1.2
`----
and also add the port
,----
| Port 993
`----
For the local dovecot, I had to add this
,----
| AuthMechs LOGIN
`----
Since my email provider uses Microsoft Exchange (or Outlook or Office365
or whatever they call it these days), I had to add a couple of options
to go around bugs in their server. These are documented in [1] and [2].
FWIW, my final mbsync config looks like this:
#+begin_src conf :tangle mbsync/.mbsyncrc :mkdirp yes
IMAPAccount garjola
Host imap.domain.net
Port 993
User login@domain.net
PassCmd "emacsclient -e \"(my/lookup-password :host
\\\"imap.domain.net\\\" :user \\\"login@domain.net\\\")\" | cut -d '\"'
-f2"
SSLType IMAPS
SSLVersions TLSv1.2
CertificateFile /etc/ssl/certs/ca-certificates.crt
PipelineDepth 1
Timeout 120
IMAPStore garjola-remote
Account garjola
IMAPAccount garjola-dovecot
Host localhost
User login@domain.net
Pass passwurd # local password I don't care much about
SSLType None
AuthMechs LOGIN
IMAPStore garjola-local
Account garjola-dovecot
Channel garjola
Master :garjola-remote:
Slave :garjola-local:
Patterns *
Create Both
Expunge Both
Remove Both
#+end_src
The configuration of dovecot (dovecot.conf and passwd) don't need any
change. And nor does the .gnus part.
To look up the imap password, I use this (stolen from [3]):
#+begin_src emacs-lisp
(defun my/lookup-password (&rest keys)
"Lookup a password using auth-source"
(let ((result (apply #'auth-source-search keys)))
(if result
(funcall (plist-get (car result) :secret))
nil)))
#+end_src
Cheers,
Garjola
