Hi fellow Postfixers,

I've encountered an interesting anomaly in the mailserver I'm currently
administrating.

I'm not the one who installed it, and it's been running fine for a long
time.

Postfix uses a mysql DB for users/passwords/domains etc.

There are a lot of domains running on this server. All work well with
their own e-mail accounts.

However, when receiving an e-mail from info (this goes
for all domains) it rewrites the sender to

info (which is also a valid domain and user on this server),
so a reply to an e-mail from info would

never arrive at the actual sender, but at info

This only happens for user "info", other users are not affected.

I've been looking into rewriting, canonical, virtual maps etc. but
couldn't find any specific line about user "info"

Could anyone point me in the right direction ?

Regards,

Jaap Westerbeek
