Postfix + Dovecot + sieve (vacation) not working for email aliases - FIX

[paknet]

I found out (well one of our customers did), that auto-reply sieve script (vacation - via Roundcube) is not working, when mail is sent to one or more email aliases.
But if you send an email to actual user auto-reply works just fine.

After a few hours of googling i found a solution for this problem...

You need to edit /etc/postfix/master.cf

Find...

Code:

# Dovecot LDA dovecot   unix  -       n       n       -       -       pipe  flags=DRhu user=vmail:mail argv=/usr/libexec/dovecot/deliver -d ${recipient}

and replace it with...

Code:

# Dovecot LDA dovecot   unix  -       n       n       -       -       pipe   flags=DRhu user=vmail:mail argv=/usr/libexec/dovecot/dovecot-lda -f ${sender} -d ${user}@${nexthop} -a ${original_recipient}

Done!
