Tutorial doesn't work under debian lenny. It doesn't install 1.2. Probably because of the missing "-t lenny-backports" after "sudo apt-get upgrade dovecot-imapd dovecot-pop3d".

There's also another Problem which is stopping dovecot from starting up. In my dovecot.conf I had to comment out following lines under "protocol managesieve"

    sieve = /var/vmail/sieve/%Ld/%Ln/dovecot.sieve
    sieve_storage = /var/vmail/sieve/%Ld/%Ln/

and those two lines had to be added into a plugin tag. There was already one with just "sieve=", so I just added sieve_storage to it.

# Per-user sieve mail filter.
plugin {
    # For maildir format.
    sieve = /var/vmail/sieve/%Ld/%Ln/dovecot.sieve
    sieve_storage = /var/vmail/sieve/%Ld/%Ln/
}

After those fixes dovecot starts without a problem.

Hi !

I have many problems with this. Look this erros in conf:

Hi,

when I follow the tutorial of upgrading dovecot under Debian lenny the upgrade process wants to upgrade several other packages.
Because there is no hint in the tutorial I aborted upgrade.
So my question is if it's ok to upgrade also all other packages?

root@mail:/var/vmail# apt-get -t lenny-backports upgrade dovecot-imapd dovecot-pop3d

Thanks!

PS: and also thank you for this great mail solution!

ok, I am back...

After the upgrade and the changes described in the wiki first all seem's ok, receiving mails is fine.
But then I tried mail sending and got the following error:

Dec 13 12:05:14 mail postfix/smtpd[23043]: warning: when SASL type is "dovecot", SASL path "dovecot-auth" should be a socket pathname

Sending mails fails. And I do not see the error because the authentification part was not touched...

Can you please help me again?

Finally I found another error:

Dec 13 11:59:44 deliver(www-data): Error: sieve: failed to stat user's sieve script: stat(/var/vmail/sieve//www-data/dovecot.sieve) failed: Permission denied (euid=33(www-data) egid=33(www-data) missing +x perm: /var/vmail) (using global script path in stead)
Dec 13 11:59:44 deliver(www-data): Error: sieve: main_script: failed to stat sieve script: lstat(/var/vmail/sieve/dovecot.sieve) failed: Permission denied (euid=33(www-data) egid=33(www-data) missing +x perm: /var/vmail)

Dec 13 11:59:44 deliver(www-data): Error: sieve: failed to open script /var/vmail/sieve/dovecot.sieve

This occurs when the awstats cron job tries to send mail to a mailaccount which had have working sieve rules before upgrade.
