[Dovecot] receive date wrong in outlook
by Farkas Levente 01 Nov '07

01 Nov '07

hi, we migrate from exchange to dovecot. we do it with imapsync. first we try to do it with --syncinternaldates, but this fails on many messages with invalid date, so we drop this option. unfortunately after this those users who use outlook see the received date as the date we do the migration in stead of the real received date. other clients eg webmail, thunderbird etc sees the right date. so my question what can i do? it's a dovecot bug or outlook and if outlook's bug is there any workaround fro this? thanks in advance. -- Levente "Si vis pacem para bellum!"

[Dovecot] Authentication
by Isaac Scott 31 Oct '07

31 Oct '07

Hi I am looking to use dovecot with postfix/amavis/spamassasin and would like to be able to deliver spam/virus emails into specific virtual user folders. I wanted to know if it is possible to authenticate user for IMAP and POP3 access seperately using a database? All I have seen in the documentation/wiki is a single query for authentication. Regards, Isaac

I have problem with dovecot-1.0.3 and apacheds ldap server. If I change just uris in dovecot-ldap.conf to point to fedora-ds server, everything works O.K. I've tried with apacheds ldap server versions 1.0.2 and 1.5.0 command line search with parameters taken from dovecot.debug log gives me all needed attributes. Comments and help welcome.

[Dovecot] Sometimes Dovecot v1.0.3 does not accept new connections
by Steffen Kaiser 30 Oct '07

30 Oct '07

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello, occasionally Dovecot stops to accept new connections. Already existing ones do function properly. Strace'ing dovecot-auth reveals that it is running and is authentificating users, the logfile logs new connections. However, lots of other connects just stall, before the IMAP server responds with the greeting. My user backend is a LDAP server. I've sniffed the interface, but I also don't see numerous connection attempts, so I suppose, that there is no DoS attack running. The logfile contains no warning or error except: dovecot: Oct 17 15:34:44 Warning: auth(default): Growing pool 'plain_auth_request' with: 2048 dovecot: Oct 17 15:34:49 Warning: auth(default): Growing pool 'plain_auth_request' with: 2048 dovecot: Oct 17 15:34:52 Warning: auth(default): Growing pool 'plain_auth_request' with: 2048 dovecot: Oct 17 15:35:02 Warning: auth(default): Growing pool 'plain_auth_request' with: 2048 dovecot: Oct 17 15:35:05 Warning: auth(default): Growing pool 'plain_auth_request' with: 2048 dovecot: Oct 17 15:35:12 Warning: auth(default): Growing pool 'plain_auth_request' with: 2048 dovecot: Oct 17 15:35:19 Warning: auth(default): Growing pool 'plain_auth_request' with: 2048 dovecot: Oct 17 15:35:20 Warning: auth(default): Growing pool 'plain_auth_request' with: 2048 dovecot: Oct 17 15:35:25 Warning: auth(default): Growing pool 'plain_auth_request' with: 2048 dovecot: Oct 17 15:35:26 Warning: auth(default): Growing pool 'plain_auth_request' with: 2048 dovecot: Oct 17 15:35:27 Warning: auth(default): Growing pool 'plain_auth_request' with: 2048 dovecot: Oct 17 15:35:27 Warning: auth(default): Growing pool 'plain_auth_request' with: 2048 dovecot: Oct 17 15:35:41 Warning: auth(default): Growing pool 'plain_auth_request' with: 2048 dovecot: Oct 17 15:35:42 Warning: auth(default): Growing pool 'plain_auth_request' with: 2048 dovecot: Oct 17 15:35:47 Warning: auth(default): Growing pool 'plain_auth_request' with: 2048 dovecot: Oct 17 15:35:49 Warning: auth(default): Growing pool 'plain_auth_request' with: 2048 dovecot: Oct 17 15:35:49 Warning: auth(default): Growing pool 'plain_auth_request' with: 2048 dovecot: Oct 17 15:35:50 Warning: auth(default): Growing pool 'plain_auth_request' with: 2048 dovecot: Oct 17 15:35:56 Warning: auth(default): Growing pool 'plain_auth_request' with: 2048 dovecot: Oct 17 15:36:03 Warning: auth(default): Growing pool 'plain_auth_request' with: 2048 Does somebody has an idea, where to go to look into the issue?

[Dovecot] 1.1Beta5 Issue
by Jeff Grossman 30 Oct '07

30 Oct '07

I installed 1.1Beta 5 this weekend. I had no problems at all yesterday using Thunderbird. I started reading my mail with Squirrelmail this morning and everything was going pretty smooth. I tried to delete a daily e-mail I receive from careerbuilder.com and the IMAP process shot up to 99.9% and I was not able to do anything in Squirrelmail. I killed that process and tried it again just to be sure what it was. And it did it again. I can delete any other message with no problems, just that one causes me issues. I am not sure if Thunderbird is the same, I will have to wait until I get home tonight. If there is any troubleshooting you would like me to do, please let me know. Jeff

[Dovecot] time going back
by zbigniew szalbot 29 Oct '07

29 Oct '07

Hi all, Sorry if this is trivial. I am just concerned. In Poland we will be putting the clocks one hour behind (back) on Sunday. I once saw dovecot killing itself because I manually adjusted the clock in the past. Will it not happen in this case? Thanks for your ideas. Zbigniew Szalbot

[Dovecot] Static home while using LDAP
by David Bosque 29 Oct '07

29 Oct '07

Hello all, I've been googling for a workaround for this for nearly a week to no avail and I hope someone in the list can shed some light on it. I have downloaded and compiled dovecot 1.0.5 and applied the quota-warning to it. I have configured everything and it's working wonderfully, even the lda with the sieve plugin. This is my current relevant configuration: userdb static{ args = uid=501 gid=12 home=/var/mail/buzones/%d/%n allow_all_users=yes } passdb ldap { args = /etc/dovecot/dovecot-ldap.conf } However, I need to obtain some more data from LDAP, so I need to switch to an ldap userdb, but want to keep the home as it is in the static configuration and not having to store it in LDAP. Is it possible to use a fixed home (as in the static userdb) while using an ldap userdb? I am looking for something similar to user_global_uid and user_global_gid but for the "home". If not, is it possible to fix or append something to the values in the user_attrs (like the following)? user_attrs = [whatever_i_want_to_append]uid=home uidNumber=uid,gidNumber=gid Regards, David Bosque
