AW: [suse-security] Filter out bad emails

by Rasp, Robert

Hello, i know about the patch. This patch only helps, if qmail is used as server. I use qmail as relay and virus-protection. The unwonted mails came from our own Exchange-Server. Because he wants to tell the (not existing) sender about a not existing emailadress. CU Robert -----Ursprungliche Nachricht----- Von: Theo v.

Vacation and out of office autoresponders

by Carlos E. R.

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, I got not less than 5 autoresponses from vacation type programs for a single message I posted to this list, on the "Execute a SSH command" thread. Is that the normal behaviour normal here? I don't understand how people interested on security can be so careless with autoresponders :-/ :-O These are the culprits - I name them so that they can know what is happening, if they really read the list: 1) t.foecking#kreis-borken.de robin1.listas#tiscali.es betreff Mailer Dämon - Unknown User Die Nachricht an t.foecking#kreis-borken.de konnte nicht zugestellt werden.

Filter out bad emails

by Rasp, Robert

Hello, i use qmail with spamassassin and qmail-scanner. As you all know, most of the spamers generate emailadresse by them mself and try to deliver ther sh** to the "new recepient". The LINUX-Box is only our relay. In the back is a Exchange-Server working. The EX-Server trys to answers to the non existent mailadress of the spammer. Spamassassin has already markted this mails as spam. How can i use MAILDROP (or someting else) to kill this mails. Because this mails make my queue on the qmail-Server grow and grow ... Its not allowed to me to drop all mails marked as spam. But its allowed to drop mails, marked as spam which are send from our own Postmaster. thanks for your Help Robert Rasp
