[Dovecot] RC8 - Creating maildir
by Luigi Rosa 11 Oct '06

11 Oct '06

I just setup a new mail server with maildir and Dovecot RC 8 I noticed that when I login via POP3 with a username that do not have a maildir yet Dovecot logs this line: Oct 11 11:46:52 gw dovecot: stat(/var/spool/mail/xxxx/) failed: No such file or directory After that Dovecot correctly creates the maildir structure Wouldn't it be better to log a message like "Creating maildir structure for user xxxxxx"? Ciao, luigi -- / +--[Luigi Rosa]-- \ I didn't know it was impossible when I did it.

[Dovecot] Executing SQL update upon login
by Tom Sommer 10 Oct '06

10 Oct '06

Hi, I'm using SQL authentication in dovecot, and was wondering if anyone had any ideas as to how I could run an UPDATE statement upon each login, to set time of last login (and other interesting stuff) in the database table. -- Tom

[Dovecot] How Dovecot handles email changed by file operations
by Craig Jackson 10 Oct '06

10 Oct '06

Hi, We have been using Courier-imap for a few years. I am always in the process of reviewing competing software, and hence my interest in Dovecot. Question: If email files are moved between IMAP folders (on the same IMAP server or a different one) or deleted using shell scripts, how does this impact Dovecot's indexes or its method of keeping track of the email? How likely is index or file corruption or race condition? An example, is the centralized removal of mail in all users' Junk folder older than 30 days. We use Maildir format and Dovecot 1.0-RC7 with Mysql. We have about 150 users. Thanks. Craig

So it doesn't look like a memory leak here. The proxies are running great. Thanks, Bill

Try running "dovecot --version" to check. As for the other (if it's unrelated) what do you have for "max_mail_processes"?

[Dovecot] POP3 - Mark messages as read
by Jose Gervasio Gomiz 10 Oct '06

10 Oct '06

Hi all. I have a little problem with Dovecot. My POP3 users can retrieve their emails without problem, but if they have "Leave mail in server" (or similar) active in their clients, their mboxes doesn't get updated marking those messages as read. If I access their mboxes locally with "mail -f username" I can see every message marked as non-read, something that never happened before when I used qpopper. I should note that when they retrieve their emails afterwards those previously received doesn't arrive again (correct behavior). My setup is: RHEL 4 Update 4 dovecot-0.99.11-4.EL4 (last version in RH Updates) mbox format, external POP3, local only IMAP (Squirrelmail) I couldn't find references to this in /etc/dovecot.conf, the FAQ or via web searching. Should I upgrade to dovecot-1.x to solve this? Even if RH doesn't support it yet? Any info would be greatly appreciated. Jose Gomiz

[Dovecot] RC8 failing...
by Timothy Meader 10 Oct '06

10 Oct '06

I just tried upgrading from RC7 to RC8 this morning, and I'm seeing an issue I've never seen before. On my first POP3 login, all is fine, but any subsequent logins seem to fail with the message: dovecot: Oct 10 11:04:31 Error: Maximum number of mail processes exceeded In the dovecot log file. I'm also oddly seeing the message: Oct 10 11:01:05 popbkup pop3-login: [ID 799321 mail.crit] Dovecot version mismatch: Master is v1.0.rc7, login is v1.0.rc8 (if you don't care, set version_ignore=yes) in the messages file on my system. Don't really understand that one, and I've done a complete shutdown of all dovecot or *-login *-auth processes prior to the "make install" for RC8. The only possible config file change I can think of that might've caused this (that was mentioned in the release notes for RC8) is the default_mail_env value, however, I believe mine is fine: mbox:~/mail:INBOX=/var/mail/%1u/%1.1u/%u This is for an actual mailbox with a two character hash for the maildrop directory. I was looking forward to giving RC8 a spin, but I've had to revert back to RC7 for now.
