Hello ppl,
I'm using postfix has relay and sometimes appear some messages with 
multiple senders,

from outside but with my domain, like

From: j...@domain.xx, a...@domain.xx, ...

How can I avoid/delete this messages or mark them like spam in 
spamassassin?

thanks in advance


Hi,

I am having the same issue for the last time.
What I made was to do regexp check:

header_checks = regexp:/etc/postfix/header_checks

and in file header_checks:
/^From:[ ]*[a-zA-Z0-9]*\@domain.xx[,]*.*$/     REJECT Sorry! No 
domain.xx in FROM
