We've been trying to stop relay raping and UCE in general through
our system and so far, badmailfrom, rcpthosts, tcp-wrappers with
/etc/hosts.deny seems to be almost completely useless or block our own
users from sending/receiving email. I am a techie, but I've been doing
managment/finance/etc so my tech side is very rusty.
I'm looking at the following options:
1) Converting back to sendmail, is there information on how to do this or
any conversion program to convert backwards but keep the maildir format?
No flames please, we converted to qmail solely due to security problems
with sendmail 3 years ago, sendmail seems to have finally gotten the
bugs out. The performace enhancement was nice, I've seen the spam
relayers shove 10K+ emails/hour through us and I'd like to stop that.
2) Is there anyway to have qmail check for certain text strings in either
the headers and/or entire message and reject a message based on the header
content, ie, alot of spam says things like From: some [EMAIL PROTECTED]
3) Can qmail be setup so we use a machine with sendmail as the spam
filter and then have it pass the mail to qmail for deliver?
4) Other suggestions?
One of the complications we have is we're running a couple hundred or
so virtual domains and some of the users are not local to our network,
they connect via aol.com, earthlink.net, etc.
