Topic: Howto block some spam emails.
I have mail domain skeurochem.pl.
Many of spam messages i'm receiving is using in "from" field skeurchem.pl email account.
From: Genuine Pfizer c Retailer <firstname.lastname@example.org>
Received: from bzq-84-110-52-4.red.bezeqint.net (unknown [22.214.171.124])
Is it possible to block this kind of spam, just make a limitation (you can use in mail from server skeurochem.pl if you are using auth smtp) ?
