Hi, i never used dovecot so far, but i heard a couple good things about it .. for one the debian maintainer of the exim package recommended it :-) so i want to change our mailserver (currently using ipop3 and uw-imap) to dovecot ... now my boss seems to favour cyrus. i could use some good arguments for dovecot, also your experiences with it and with other mailservers so i can make a reasonable desicion and preset some good arguments :-) Florian

I'm trying to switch to imap from pop3, so I set up dovecot on my Slackware 10.2 mailserver. I'm very new to imap, so I figured my configuration was wrong. If our symptoms are the same, maybe our setup errors are as well. The problem... while Thunderbird and Outlook are OK, the Inbox doesn't show in Outlook Express. You can click on the Imap Folders button, select the Inbox, click on the "Go To" button and the Inbox will appear until you shut down Outlook Express. Next time you fire up OE, no Inbox. Other than that, it all works as expected. I haven't torture-tested the setup yet though, I wanted to set up one of each client and get the basics running before doing that. Are your symptoms similar? Here is my dovecot.conf less comments... ssl_cert_file = /etc/mail/certs/wally.cert.pem ssl_key_file = /etc/mail/certs/wally.key.pem first_valid_gid = 100 mail_extra_groups = "mail" namespace private { separator = / inbox = yes prefix = "#mbox/" location = mbox:/var/spool/mail/%u } namespace private { separator = / prefix = location = maildir:/data/imap/%u } protocol imap { imap_client_workarounds = outlook-idle } protocol pop3 { } auth_realms = "laframboise.net" auth default { mechanisms = plain passdb shadow { } userdb passwd { } userdb prefetch { } user = root }

[Dovecot] mailserver pop3-login: Disconnected
by Shawn Bishop 13 Dec '05

13 Dec '05

Good Day I am having the following serious problem. I am running CentOS 4.1 with dovecot 0.99.11. The users are using POP3 login to retrieve mail. For the last 2 days we have experienced the following problems. I have recreated all the users and reconfigured the dovecot,but the same problems occur. Please see attached /var/log/maillog messages It appears so users login whereas others cant.Eventually after about an hour none of the users can login.

[Dovecot] Case sensitive nightmare
by Erik Petersen 12 Dec '05

12 Dec '05

It took me 4 days to figure this out and I sure hope someone can help me solve it. My Setup: Postfix + MySQL + dovecot dovecot.conf: default_mail_env = maildir:/var/spool/vmail/%d/%n/Maildir password_query = SELECT password FROM mailbox WHERE username='%u' user_query = SELECT maildir, 108 AS uid, 108 AS gid FROM mailbox WHERE username='%u' The virtual host schema is postfix.admin compatible but I¹m not using it (phpMyAdmin is actually easier to use). When foo(a)domain.tld, abrand new account, logs in using an IMAP client (any client; squirrelmail, OE, tbird, Apple...) a maildir is created named domain.tld/foo/Maildir¹ and everything is good. Now I login as Foo(a)domain.tld and then as fOo(a)domain.tld and then as foO(a)domain.tld then so on for every case variation. Each of these accounts can login correctly, they are seen as being the same account by dovecot. On the other hand they are not seen as being the same mailbox! When I check my mail spool I see one maildir for every case variation (domain.tld/foo/Maildir, domain.tld/FOO/Maildir, etc.) It would seem to me that the queries above would fail for the different variations of the name but they don¹t seem to. Is dovecot converting %u to lower case for the query on the virtual users table but then using it unconverted when looking up the Mairdir for the account? If the username column has the value foo(a)domain.tld1 how does SELECT * FROM table WHERE username=¹FOO(a)domain.tld1 match the row? Also puzzling is that I select a column named maildir which has the path to the mailbox in it (using the correct case). Even if SELECT pigs fly¹ AS when WHERE FoO¹=¹foo¹ the maildir path for the account is being returned which is domain.tld/foo/Maildir¹ so how does domain.tld/FoO/Maildir¹ get created? This is both a pain in the nuts support nightmare but also a security problem (albeit fairly limited). An account named ³barneyrubble² could generate a significant number of maildir directories if you logged in with every variation thereof. Any assistance would be greatly appreciated. Thanks
