[Dovecot] disable lazy_expunge for some mailboxes?
by Frank Cusack 03 Jan '10

03 Jan '10

How to disable lazy_expunge for certain mailboxes? My problem is I have a public namespace, whose mail is on a different filesystem than user mails. Some users are allowed to expunge on this shared mailbox, but lazy_expunge is stopping that from working since the mail has to cross a filesystem boundary to make it into the lazy_expunge namespace (location is under the user's home directory). As a workaround can I run a daily cron job to remove messages with the \Deleted flag on them? If so how do I find them? thanks -frank

[Dovecot] 1.2.9 -llber
by Frank Cusack 02 Jan '10

02 Jan '10

1.2.9: configure: Added -llber to ldap libs. Fixes linking in some systems. and breaks it on others. Sun Solaris' native ldap library does not have a separate liblber. I normally check for ber_free in libldap, then in liblber, then fail. -frank

[Dovecot] Recalculate quota usage on demand
by Michael 02 Jan '10

02 Jan '10

I would a method for Dovecot to recalculate the quota usage and rewrite it to the quota DB (Called on demand by a non-Dovecot POP3 daemon) I don't want the line deleted in the DB as this would only recalculate next time the Dovecot LDA or IMAP handles a message, and I want to keep the data availability contiguous. Can this be done?

[Dovecot] nested folders
by Jim Pazarena 02 Jan '10

02 Jan '10

using both thunderbird and roundcube with dovecot IMAP, I can create all the folders I desire, but cannot create subfolders; I also cannot delete a folder once created. I get a very un-informative error message from each. Is there a special setting required to permit sub-folder creation? folder deletion? I've got 770 mail:mail virtual_user_home 770 mail:mail mail_sub-directory 770 mail:mail .imap 660 mail:mail .subscriptions 700 mail:mail Drafts 700 mail:mail INBOX 700 mail:mail Junk 700 mail:mail Sent 700 mail:mail Trash Suggestions would be appreciated. Thanks!

[Dovecot] Using Push IMAP to trigger POP3 download
by Aaron Whitehouse 02 Jan '10

02 Jan '10

Hello all, I have an HTPC connected 24/7 to the Internet running Mythbuntu. I also have a web/email host that runs Dovecot for email and provides IMAP and POP3 access. I understand that Dovecot supports Push IMAP and I could, for example, use Thunderbird to connect to my email host to receive instant email as it arrives. I would like to add a Dovecot IMAP server on my HTPC (for increased storage, to aggregate multiple email accounts, to process messages with SpamAssassin and to provide a better webmail interface) and retrieve email from my webhost to my HTPC by POP3. To set up POP3 on my HTPC, I understand that the norm is to set a time interval (say, every 10 minutes) for clearing email. What I would prefer to do, if possible, would be to have Dovecot on my HTPC keep a Push IMAP connection with Dovecot on my webhost. When a new message is available on the webhost, my HTPC would be "pushed" a notification and it could do a POP3 download. This would allow it to clear emails with POP3 (and reduce storage requirements on my webhost), mean that I received emails instantly and not require me to have it poll for messages on a very-regular basis. Does anybody know if this is possible? As an alternative (not solving my space problem on the webhost, but solving the others), is it possible to set up Dovecot to "piggy back" off an existing IMAP server? In my example, my webhost does not offer good spam-checking and webmail. Would it be possible for me to set up a Dovecot server on my HTPC that received messages by Push IMAP, processed them with SpamAssassin (say, moving all of the spam messages to a subfolder) and provided a good web interface, all the while providing updates to the webhost's server? In some ways, this is almost more like an IMAP client than a server. I apologise if these questions are stupid! Happy New Year and thanks in advance, Aaron -- FSF Associate Member: 5632 http://www.fsf.org

[Dovecot] Deliver virtual user's mail to a specific namespace?
by Brian Schang 02 Jan '10

02 Jan '10

Hello: I have virtual users set up for the various mailing lists that I subscribe to. Everything has been working well in both Postfix and Dovecot. Postfix is configured to deliver to a specific mbox file within my mbox mail root. I can access retrieve and read email via Dovecot without any issues. Now I want to make my setup more robust and have these messages delivered to a maildir namespace. I have configured the LDA within the Postfix master.cf file: dovecot unix - n n - - pipe flags=DRhu user=vmail:vmail argv=/usr/lib/dovecot/deliver -f ${sender} -d ${recipient} I have configured the 'dovecot' transport within Postfix in the transport file: test(a)lists.schang.net dovecot: In dovecot.conf I have set up the namespace as follows: namespace private { separator = / prefix = "Lists/" location = maildir:~/MailLists subscriptions = yes } I'm having a hard time specifying the "Lists/" namespace in my userdb passwd-file: test:{PLAIN}linux:2000:200::/home/brian::userdb_mail=maildir:Lists/test I can't get the userdb_mail portion to work. For this user, 'test(a)lists.schang.net', how do I tell Dovecot/deliver to put the message in the 'test' mailbox within the 'Lists/' namespace? I'd appreciate any insight. Thank you. -- Brian Schang

[Dovecot] Issue Authenticating to a new dovecot-postfix installation
by Anthony Nedland 02 Jan '10

02 Jan '10

(Apologies if this is a resend, but I thought I had received a bounceback message.) I have installed dovecot-postfix and postfixadmin on an Ubuntu 9.10 machine. The userdb and passdb are both mysql. If I set up a user in postfixadmin they are able to send. I can successfully telnet into the server remotely by name on 110 and 25. I'm not looking for any authentication encryption/ssl any of that, just POP3/SMTP. When I telnet into 110 I can enter a username with user [username] then when I do pass [password] I get -ERR Authentication failed. I know the user info is correct. When I set up an account in Outlook Express I get "There was a problem logging onto your mail server. Your Password was rejected:" Also saying -ERR Authentication failed.'. (0x800ccc90,0x800ccc92) So basically the same thing. I can attach the tutorial I used in as a .doc if that would help. Anyway, here is my relevant info I think. -- -- -- Version 1.1.11 -------------------------------------------------------------- ---------------------------------------------------------------- ----------------------------------------------------------------- dovecot-sql.conf GREP driver = mysql connect = host=localhost dbname=postfix user=postfix password=password default_pass_scheme = PLAIN user_query = SELECT '/var/vmail/%d/%n' as home, 'maildir:/var/vmail/%d/%n' as mail, 150 AS uis, 8 AS gid, concat(dirsize:storage=',quota) AS quota FROM mailbox WHERE username = '%u' AND active = 1 password_query = SELECT username as user, password, '/var/vmail/%d/%n' as userdb_home,'maildir:/var/vmail/%d/%n' as userdb_mail, 150 as userdb_uid, 8 as userdb_gid FROM mailbox WHERE username = '%u' AND active = 1 -------------------------------------------------------------- ------------------------------------------------------------- ------------------------------------------------------------- root@mail:/etc/dovecot# dovecot -n # 1.1.11: /etc/dovecot/dovecot.conf Error: Error in configuration file /etc/dovecot/dovecot.conf line 1076: Unknown section type (section changed in /etc/dovecot/dovecot.conf at line 1038) Fatal: Invalid configuration in /etc/dovecot/dovecot.conf Starting line 1076---> master { # Master socket provides access to userdb information.

They refer to dovecot.conf though. The config file is clearly dovecot-postfix.conf so I am confused as to why the other matters. I had noticed changes only when I changed dovecot.conf though. (In dovecot -n output)

[Dovecot] Dovecot LDA with SetUID
by Michael 02 Jan '10

02 Jan '10

Has anyone been able to get Dovecot LDA working where each user has a different UID? All the howtos on the Internet I have found set the UID of a mailbox as fixed for all users. However I have tried to run it on the current SQL database we have (with different UID per user) and I get the following: Jan 1 16:25:40 HOST dovecot: deliver(EMAIL): Fatal: setgid(1000(stdusers)) failed with euid=8(mail), gid=12(mail), egid=12(mail): Operation not permitted I am calling this from Postfix with: dovecot unix - n n - - pipe flags=DRhu user=mail:mail argv=/usr/local/libexec/dovecot/deliver -f ${sender} -d ${recipient}

[Dovecot] Quota with Dict + SQL not updating
by Michael 01 Jan '10

01 Jan '10

Hello all, I have a Dovecot server deployed with a MySQL back end. If the user logs in and there is no quota set for them in table 'quota', the system will automatically inset a line with their username and current messages/storage. However after this it fails to update the information when to reflect new messages coming to their inbox after the original insert of the information. It will only update the information when a user deletes a message. Why is it not updating this information every time their mail is checked with IMAP? Cheers, Michael
