[Dovecot] get username of logged in user
by Stefan Jurisch 15 Jan '09

15 Jan '09

Hello, can I anywhere get the name of the currently logged in user? I'm still implementing a custom ACL plugin (IMAP commands MYRIGHTS, GETACL, SETACL, DELETEACL), and for some functions (for example storing the current folder's ACL in combination with this username) I need to obtain the currently logged in IMAP user. Is this possible? If yes - how? Thanks in advance.

[Dovecot] ImapTest Wiki
by Justin Krejci 15 Jan '09

On this page http://imapwiki.org/ImapTest/Running It gives command line parameters to define. One of them is "password=pass" but this resulted in an "Unknown arg" response for me on a fresh install. I then looked at some examples and they give the argument as "pass=pass" which works for me. Was the argument name changed recently or something?

[Dovecot] Personal dovecot

Do you think it wold be worthwhile to add command line options to "deliver" and "imap" to make them ignore "system wide" configuration file and use ~/.dovecotrc instead? I would like to use "imap via fetchmail ssh plugin" and "deliver via ~/.forward (to get sieve support)". Such options would allow "cleaner" configuration. -- [pl>en: Andrew] Andrzej Adam Filip : anfi(a)onet.eu : anfi(a)xl.wp.pl Nice boy, but about as sharp as a sack of wet mice. -- Foghorn Leghorn

[Dovecot] ldap performance?
by Jan-Frode Myklebust 15 Jan '09

15 Jan '09

We're looking at replacing our mysql auth and userdb, with a set of Red Hat Directory servers, and I see dovecot supports either authentication binds, or "password lookups": http://wiki.dovecot.org/AuthDatabase/LDAP I'm curious if anybody can give any insight as to what kind of performance to expect from authentication binds ? How many POP3s/second should we expect from it ? Our directory servers will be 2 blades with 4 cores of 2GHz each, and we expect to keep the full directory in memory on both servers. -jf

[Dovecot] Apple patch 9
by Mike Abbott 15 Jan '09

15 Jan '09

Patch #9 adds support for Open Directory and an encrypted SSL keystore. Notes about this patch: It adds --enable-apple and --with-od options to configure (after running autoconf). It depends on patch #7 (hash_table_create/destroy). Automake wipes out this patch's changes to Makefile.in. The - framework options should come from Makefile.am but the author didn't do that. It uses a tab-stops-every-4 indentation style. It may compile and run only on Mac OS X 10.6, currently available via Apple Developer Connection. This code is stable but Apple is still verifying its robustness. This is the patch that needs the user name as extra_fields[0] in deliver, to handle user name aliases. More patches to come, probably after the holidays.

[Dovecot] Maildir++ quota: When is it recalculated?
by Ulrich Zehl 14 Jan '09

14 Jan '09

We use Maildir++ quota, with the rules taken from our LDAP backend. We also have an old expunge script that's not quota-aware; it removes old messages from the maildir by simply deleting the files. Sometimes, a mailbox is over quota before the script runs, but well under quota after the old messages are deleted. This change does not seem to be picked up, however: When I try to deliver a new message (using Dovecot's deliver), the attempt fails with an "over quota" error. I tried finding out from the source code whether this is intended behavior, but unfortunately, I'm not enough of a programmer, so I have to ask here: Should I be able to delete mails from a maildir, and expect the quota plugin to notice the change? We use Dovecot 1.1.8, by the way. Ulrich
