Hello Steffen,
thank you for creating a test setup. I will try to implement it the way
you did it, but I will stay with maildir.
Meanwhile I have recognized another issue, this time with our webmail
system (roundcube). It seems that it is not able to handle multiple
namespaces so I might need to stay with the single private namespance setup.
Thank you very much for your kind help.
best regards
Andreas

try upgrade roundcube with reconfigure
some issues with namespace were solved
http://trac.roundcube.net/ticket/1486796
http://trac.roundcube.net/attachment/ticket/1486796/imap_namespace.patch
however i am not sure if that fixes your special problem

[Dovecot] dovecot-2.2.beta1: do not removes e-mail with enabled replication
Hello.
I'm created two installations of dovecot-2.2.beta1 with identical
config. Without replication each server works good. With replication
enabled every changes are replicated between these ones.
When I probe remove or move some email in another folder it is
disappears and reappears again and again in source folder and appears in
destination folder. Thus increasing number of letters like with copy.
Possible reasons cause of the problem:
- bug
- configuration settings of dovecot
- users with wich dovecot works and users rights.
Which version is true? If this not a bug, what should be corrected in
the configuration?

[Dovecot] Reviewing end-user ham/spam submissions before feeding them to sa-learn via Dovecot Antispam plug-in
Currently, I'm using the Dovecot Antispam plug-in with great success. Everything works as expected. However, I would like to change the plug-in's behavior such that it simply sends a copy of a message that is moved from Inbox - Junk (or Junk - Inbox) to an administrator, instead of calling sa-learn (I'm using SpamAssassin) automatically. Basically, I would like to be able to review messages that end-users submit for training before they are actually fed to sa-learn. Has anyone had a similar need? If the Antispam plug-in already supports this, if the necessary commands can simply be added to the shell script that Antispam calls, or if there is a better method altogether, any help is greatly appreciated. Thank you! -Ben

moving mail from/to spam folders.
antispam plugin is loaded and imap service itself runs correctly

When I move mail into or out of imap folders named Junk or SPAM I would
expect, that the antispam plugin kicks in and pipes the mail to dspam.
Apparently this does not happen, nothing gets piped, though the mail is still
moved to the folder.
I've already tried dspam-exec as a backend as well, but that fails even ealier
right after imap login with:

[Dovecot] Benchmarking: Dovecot vs Courier. Courier wins as POP3 server
Hi All,
I have compared Dovecot performance to Courier and it appears that as a POP3
server Dovecot is slower in 2 times but as an IMAP server it is faster in 1.5
times. The same node (16CPUs), testing time is 30 min, please see results and
dovecot configs attached.
Benchmark software is MStone used by Sendmail Inc so is is quite reliable.
I do not see anything else to tweak in Dovecot to increase POP3 performance.
Can we all have some tips to improve it please ?

[Dovecot] failure trying to autocreate an Inbox that already exists
I have a new installation of Dovecot 2.1.12 and cannot select the Inbox without
getting this error:
c select inbox
c NO [SERVERBUG] Internal error occurred. Refer to server log for more
information. [2013-01-16 18:22:13]
Here's the server log:
dovecot[15643]: imap(u1): Error: Failed to autocreate mailbox INBOX: Mailbox
already exists
Auto create settings are currently set to 'no' -- when they were set to create,
the problem was the same. Passwords are currently plaintext for testing
purposes -- Imap authentication works.
It's running on OS/X 10.7.3 Our config is below. Thanks for any suggestions...

Re: [Dovecot] Benchmarking: Dovecot vs Courier. Courier wins as POP3 server

Can we all have some tips to improve it please ? mail_fsync = always Courier POP3 does no fsyncing. Although I'm not sure how much difference it makes with NFS. mail_nfs_index = yes mail_nfs_storage = yes Both of these are unnecessary and slow things down. Also you should add: pop3_no_flag_updates = yes

Oh, and because of Dovecot index files it has to do a bit more work than Courier, so with indexes Dovecot POP3 is probably slower for POP3 clients that download+delete all mails, but faster when POP3 clients leave (a lot of) mail lying around on the server. You could get Courier-like unindexed behavior by setting: mail_location = maildir:~/:INDEX=MEMORY
Re: [Dovecot] mbox INBOX out of sync (?)
Hello again, Permissions seems to be ok; all mboxes has 660 with group 'mail'. --- -rw-rw 1 tbarreno mail 1337814 ene 17 06:10 tbarreno --- However, the dovecot service was changed last October in Debian distro: --- * Dovecot uses two system users for internal purposes now by default: dovenull and dovecot. dovenull user is used by completely untrustworthy processes, while dovecot user is used for slightly more trusted processes. --- The dovecot user isn't included in the 'mail' group; I've tryed but it doesn't work. I'll take a look at the Postfix configuration just to see if it's locking the files. Many thanks again.

We have got mobile and desktops IMAP clients (mostly Mozilla Thunderbird). The problem is that /var/mail/ files (mbox) aren't updated: we can delete mail from clients but they persist in de /var/mail, so the same user can see the mail again from other IMAP client. Logs seems to be correct. Sounds like Dovecot thinks the INBOX is read-only. What are the filesystem permissions in the files? -- Tinguaro Barreno Delgado tbarr...@alameda.homeip.net

The same node (16CPUs), testing time is 30 min, please see results and dovecot configs attached. Benchmark software is MStone used by Sendmail Inc so is is quite reliable. I do not see anything else to tweak in Dovecot to increase POP3 performance. Can we all have some tips to improve it please ? The Middle Age has called, it wants POP3 back. --Frank Elsner
