Yes.  You just write the Perl code.

Yes.  You just write the Perl code (perhaps you see a pattern in my

MIMEDefang is extremely stable.  We have customers using our commercial
CanIt software (based on MIMEDefang) with uptimes of over 200 days.
My own commercial server has been running MD/SA/ClamAV and has an uptime of 
530 days.  Yes, uptime rolls over at 497 days.  Damn!

Stable?  Most definitly!!

MIMEDefang is a fairly decent performer.  With SpamAssassin scanning
and Clam virus-scanning, a dual Xeon at 2.4GHz with 2GB of memory
should easily handle 500 000 to 600 000 messages/day.

David.

For clamav you should switch to FreeBSD 5.X. Clamav is more stable there
(with kernel threads). We had it crashing often on FreeBSD 4.9 ...

Mimedefang does not call spamd, it has embedded support to include the
spamassassin functions itself.

Yes. You can do everthing that perl supports.

We run Mimedefang with perl 5.8.4 (from ports) in the embedded modus and
it is very stable. No crashes, no unexpected failuers. And  reload of config is
possible without stop and start.

[Mimedefang] clamav + spamassassin + virtual-domains for 500.000 mails a day

2004-06-17 Thread Florian Meister 
Hi!

I'm the mail-admin of a little internet-provider in austria.

We are using 4 mailservers (FreeeBSD 4.7 - 5.2 xeon 2x2GHz, 1GB RAM) 
and one spamserver with the same configuration. On every machine 
FreeBSD 4.7 - 5.2 is installed, depending of the age of the machine. 
On the mailservers sendmail with libmilter, spamass-milter and spamc 
is installed. On the spamserver there is a spamd running which gets 
the requests of the mailservers.

I am planning to set up a clamav-server with the same configuration.

The problem: I haven't found a milter-interface that can do something like a 
pattern-matching for the to-address to scan only specific domains, because I don't 
know how much load I get on the clamav-server. Beside of that, I want to test the 
whole thing with a test-domain.

With MIME-defang it should be possible to use spamassassin and clamav over the same 
sendmail-milter-interface. Is it also possible to check for spam in every mail 
(excluding a few trusted networks), and to check for viruses only in a few domains (or 
to-addresses) ?

Is it possible to implement a LDAP-interface ? 

How fast, performant and stable is mimedefang. I have problems with spamass-milter, it 
crashes every week. 

Thx, flo
