Hello
It seems that the connection to my imap server gets slower and slower
(I have agentized the server).
I have the following setting
(setq gnus-secondary-select-methods
'(
(nnimap "ucimap.ucm.es" (nnimap-stream network))))
Is there any way of speeding up the connection to that server, by
setting additional parameters depending on the character of this imap
server? Like setting the nnimap-server-port explicitly to 143 so
something like this.
thanks
Uwe Brauer

I think you've already done that implicitly by setting nnimap-stream to
network and thus forbidding encrypted connections. Is that really what
you want? The overhead of encrytion (if there's any) won't make a
difference compared to the normal network latency.
The only thing that will speed up things quite a lot is to install a
local imap server and let gnus connect to it. Syncing between
ucimap.ucm.es and the local server can be done with offlineimap [1], for
example.

Well yes, the 993 port is dead slow :'(

That is an interesting idea. Have you done it? Which imap server do you
recommend?

Yes.

I use dovecot. It's not too hard to configure and doesn't have a big
memory footprint. And I use offlineimap to sync my two imap accounts
with the local dovecot server.
Several others on the list use the same setup, AFAICT.

Well the devecot server is also a debian/ubuntu pkg and so I installed
it.
Is it too much to ask you for your configuration files (without psswd
and other information).
For devecot, offlineimap and gnus.
That would be a great help. I presume you run
offlineimap periodically via cron or something like this.
Maybe it would be a good idea to include such a configuration example
also in the gnus manual.
regards
Uwe
PS when using F runs `gnus-article-followup-with-original' it seems that
gnus only answers to the list but no cc to your from address, I just
wonder what is the reason for this.

Here's the dovecot config file. It ships with an example config which
describes all options, so I removed the comments here.
,----[ /etc/dovecot/dovecot.conf ]
| version_ignore=yes
| first_valid_uid = 1
| log_path = /var/log/dovecot.log
| ssl_cert_file = /etc/ssl/dovecot/server.pem
| ssl_key_file = /etc/ssl/dovecot/server.key
| mail_location = maildir:/var/spool/mail/%u
| maildir_copy_with_hardlinks = yes
|
| protocol imap {
| listen = 127.0.0.1:143
| ssl_listen = 127.0.0.1:943
| }
|
| auth default {
| mechanisms = plain
| # defines users/passwords
| passdb passwd-file {
| args = /etc/dovecot/passwd
| }
|
| userdb static {
| args = uid=mail gid=mail home=/var/spool/mail/%u
| }
| }
`----
I named the users according the foreign IMAP accounts, one user per
account.
,----[ /etc/dovecot/passwd ]
| fastmail:{PLAIN}MY_PASSWORD
| uni:{PLAIN}MY_OTHER_PASSWORD
`----
And this is the ~/.offlineimaprc:
,----[ ~/.offlineimaprc ]
| [general]
| accounts = Fastmail, Uni
| ui = Noninteractive.Basic
| maxsyncaccounts = 1
|
| [Account Fastmail]
| localrepository = FastmailLocal
| remoterepository = FastmailRemote
| quick = 0
|
| [Repository FastmailLocal]
| type = IMAP
| ssl = no
| remotehost = localhost
| remoteuser = fastmail
| remotepass = MY_PASSWORD
| maxconnections = 2
|
| [Repository FastmailRemote]
| type = IMAP
| ssl =yes
| remotehost = mail.messagingengine.com
| remoteuser = thorn@fastmail.fm
| remotepass = FOREIGN_PASSWORD
| maxconnections = 2
|
| [Account Uni]
| localrepository = UniLocal
| remoterepository = UniRemote
|
| [Repository UniLocal]
| type = IMAP
| ssl = no
| remotehost = localhost
| remoteuser = uni
| remotepass = MY_OTHER_PASSWORD
| maxconnections = 2
|
| [Repository UniRemote]
| type = IMAP
| ssl =yes
| remotehost = mail.uni-koblenz.de
| remoteuser = horn
| remotepass = OTHER_FOREIGN_PASSWORD
| maxconnections = 2
| # Don't sync shared folders
| folderfilter = lambda foldername: not re.search('Shared Folders', foldername)
`----
In Gnus I connect to the local server twice with different
users/passwords:
,----[ ~/.gnus.el ]
| (add-to-list 'gnus-secondary-select-methods
| '(nnimap "Fastmail"
| (nnimap-address "localhost")
| (nnimap-stream network)
| (nnimap-authenticator login)))
|
| (add-to-list 'gnus-secondary-select-methods
| '(nnimap "Uni"
| (nnimap-address "localhost")
| (nnimap-stream network)
| (nnimap-authenticator login)))
`----
The usernames/passwords are in my ~/.authinfo:
,----[ ~/.authinfo ]
| machine Fastmail login fastmail password MY_PASSWORD force yes
| machine Uni login uni password MY_OTHER_PASSWORD force yes
`----

Done. ;-)

Yes, I use cron. But offlineimap can run forever, checking for mail
every X minutes, too. Whatever you like best. I prefer cron so that I
can log the output and add some timestamps and stuff.

Why not. Feel free to format the configs in TexInfo and send a patch.

thanks very much, I will test this soon.

Right I will try that.
