I have a mail setup, where the SMTP server (Postfix) is running on a
machine with a public IP address, and amavisd-new and spamassassin are
running on a "filter" server in a private LAN.
Just a quick observation - does the machine on the private lan have
Internet access to perform the DNSBL lookups or can it only see the
postfix mail gateway. The amavisd-new/SA box must be able to access the
Internet to perform any tests that need Internet access.
Yes, it can download files etc. Besides, spamassassing queries
Pyzor/Razor without problems.
I just started tcpdump to see what addresses the "filter" box connects
to when it receives mail for filtering - I see:
- packets from/to the SMTP server
- packets from/to the DNS server (asking for the domain used in
MAIL FROM:<[EMAIL PROTECTED]> and Razor servers
- packets to/from 208.83.137.117, 208.83.137.115, which is Razor
- packets to/from 209.169.14.30, which is DCC
And that's it. No other DNS queries, no other packets.
