Hello,
I am using sieve with notification of the original recipient in the case that an email has been identified to contain a virus. After upgrading dovecot from 2.2.21 to 2.2.29.1, I now detected that in these notifications, their sender address is now <postmaster@>, instead of <postmaster@mailserver.domain>, like it was before. Is it possible to revert to the old format? No idea so far? Though I forgot to write that I also updated pigeonhole, the change in the format of the sender address must be caused by the updates, for I changed nothing else on my server. That looks like a bug of some sort. What is your configuration (output from
dovecot -n)? What exact Sieve script demonstrates this behavior?The output of 'dovecot -n' is attached.
It's because you have auth_username_format = %Ln, which strips away the domain.
