[Devil-Linux-discuss] Sagator as MTA?

[Mike <Mi...@4a...>]

Hi,

Our level of email backscatter has increased 600% in last 6 weeks from 
avg of 6500/day to 35,000/day and is bogging down our mail server.

My first thought was to use my handy dandy DL to solve this. So I'm 
trying to configure a DL box to act as an email filter in front of our 
mail server, so once configured and tested I'll update our MX records ( 
I have 50 domains and 1000 users) to the new DL box.

I've got clamav & spamd configured, but trying to figure out how to get 
sagator to accept the inbound mail on port 25 before relaying the good 
email on to our QMail server.

in sagator.conf I tried :

  smtpd(SCANNERS,'64.34.15.2',25),

Where the IP is the IP of the DL box, from an other machine I telnet to 
port 25 and it accepts, but when I do "helo machinename" <cr> I get no 
response and the DL box keeps the connection open until I stop sagator.

So I've obviously got something wrong, or do I have to configure postfix 
to accept and hand off to sagator?

Any input would be greatly appreciated.

Mike
