[Dovecot] transfer files from Plesk qmail to Dovecot and Postfix
by Frank Church 28 Mar '07

28 Mar '07

I have some files I want to transfer from Plesk qmail to Postfix with virtual mailboxes, MySQL, Maildir etc. I can add the accounts to the database manually as there are only a few of them. In the case of the mail folders, is it merely a matter of copying the mail files over, or are there some adjustments to be made to the files? I have noticed the thread about the Courier to Dovecot script and I wonder whether it may have a role in this process.

[Dovecot] auth server refusing connections intermittently
by Steven F Siirila 28 Mar '07

28 Mar '07

Running Dovecot 1.0-rc27 on Solaris 10.. We have been noticing intermittent messages of this sort and wondered if this indicates whether we need to add more dovecot-auth worker processes: Mar 28 03:15:41 myhost dovecot: pop3-login: Can't connect to auth server at default: Connection refused Mar 28 08:10:20 myhost dovecot: imap-login: Can't connect to auth server at default: Connection refused Mar 28 09:08:13 myhost dovecot: imap-login: Can't connect to auth server at default: Connection refused Mar 28 10:23:38 myhost dovecot: imap-login: Can't connect to auth server at default: Connection refused Mar 28 10:35:37 myhost dovecot: imap-login: Can't connect to auth server at default: Connection refused Mar 28 10:50:59 myhost dovecot: imap-login: Can't connect to auth server at default: Connection refused Mar 28 12:00:44 myhost dovecot: pop3-login: Can't connect to auth server at default: Connection refused Mar 28 12:07:31 myhost dovecot: imap-login: Can't connect to auth server at default: Connection refused Mar 28 14:44:57 myhost dovecot: imap-login: Can't connect to auth server at default: Connection refused However, this system has over 7,000 users and 1,500 simultaneous IMAP and POP3 connections, and we only see one dovecot-auth process running. By contrast, another server has over 11,000 users and 3,000 simultaneous IMAP and POP3 connections (but is currently running rc24), and we only have seen 3 of the above error messages there -- and there is only one dovecot-auth process there as well. Does this sound right? Also, how many times are these connections retried (and at what sleep interval, if any) before it gives up? -- Steven F.

[Dovecot] Removing users maildir DOVECOT+LDAP
by Venilton Junior 28 Mar '07

28 Mar '07

Hi all, Does anyone have an idea how can I remove(delete) my virtual mail users' maildir? I have Dovecot + LDAP and I would like to do something like this: When I remove an user entry in my ldap server, it should remove my user directory information. Does anyone has this implemented? Or have an idea? I can remove users entry in my ldap server remotely, is there some way in dovecot? I'm asking this, cause I'm very familiar with Cyrus and I can do this with it.

[Dovecot] Deliverm, vpopmail, and valias
by John Peacock 28 Mar '07

28 Mar '07

I'm in the final stages of testing my e-mail server to come and I seem to have hit a roadblock. One option of current vpopmail is to store all aliases in a valias table, that looks like this: +-------------+----------+------+-----+---------+-------+ | Field | Type | Null | Key | Default | Extra | +-------------+----------+------+-----+---------+-------+ | alias | char(32) | NO | MUL | | | | domain | char(64) | NO | | | | | valias_line | text | NO | | | | +-------------+----------+------+-----+---------+-------+ where valias_line could be either an e-mail address (preceded by an ampersand) or a command (piped to vacation for example). I have already accepted a message for an aliased address, but the MTA isn't going to be rewriting the envelope address, so how can I get dovecot's deliver to dereference the alias and deliver to the correct Inbox? Because of the number of other hops[1] that the message is going through, I don't want to rewrite the destination address unless I really have to, but if that is the only option, that is what I'll have to do. Thoughts? John 1) inbound e-mail hits a qpsmtpd instance which validates e-mails using several different filtering techniques. Next the mail gets fed to a dspam appliance running two Postfix queues (one before dspam and one after). Mail that isn't quarantine by dspam gets sent to the delivery server (currently running qmail) and delivered to the final destination (modulo sieve rules under deliver). The only place I could conceivably rewrite the address would be the second Postfix queue. -- John Peacock Director of Information Research and Technology Rowman & Littlefield Publishing Group 4501 Forbes Boulevard Suite H Lanham, MD 20706 301-459-3366 x.5010 fax 301-429-5748

[Dovecot] ignoring some subfolders [potential wishlist]
by Arkadiusz Miskiewicz 28 Mar '07

28 Mar '07

Hello I'm looking at migration path from my current setup (tpop3d/courier-imap) and I seem to miss one feature - ability to ignore some subfolders for pop3. tpop3d allows me to say: maildir-ignore-folders: Spam Trash trash Sent sent-mail POP3-Invisible (would be stupid to fetch own sent-mail via pop3 again 8-) In recent tpop3d cvs version I can also use regexps like maildir-ignore-folders: ^IMAP-Only.*$. Is it possible to ignore some subfolders in dovecot per protocol (like for pop3 only and not imap) ? If not then please consider this as wishlist, maybe in form of location negation like: mail_location = \ maildir:/var/mail/%Lu:!maildir:/var/mail/%Lu/.Something (which doesn't look sane) or with separate config directive like in tpop3d -- Arkadiusz Miśkiewicz PLD/Linux Team arekm / maven.pl http://ftp.pld-linux.org/

[Dovecot] problem with POP3 mail location when using namespaces
by Lutz Preßler 28 Mar '07

28 Mar '07

Hello, I have a problem (at least with 1.0rc28 and 1.0rc27) when using the following namespace definitions: namespace private { separator = "/" inbox = yes location = mbox:~/Mail:INBOX=/var/spool/mail/%u } namespace public { separator = / prefix = 0-LISTS/ location = mbox:/var/mail/lists:INDEX=~/.sharedMail/lists/index } namespace private { separator = "/" prefix = "0-MAILDIR-FOLDERS/" location = maildir:~/Maildir } IMAP access is working as expected, but when connecting with POP3(s), the (mostly empty in our case) ~/Maildir is used as mail location when it has been created (including index files) by IMAP access. If ~/Maildir does not exist/has been deleted again, POP3 uses /var/spool/mail/%u. This is independent of the private namespace section order and also an explicit "inbox = no" in 0-MAILDIR-FOLDERS namespace. Any idea if this is an configuration issue I don't understand yet or a bug?
