Does anyone know of a server/software compatible with postfix that
performs sender reputation query?
You need to be much more specific WRT "sender reputation" Roman. What
_precisely_ are you asking us to answer?
yeah.
- "sender" is ambiguous. do you mean the client IP (or the client
domain) or do you mean the envelope sender address (j...@example.com,
*...@example.org)?
- "reputation" is ambiguous. examples: "never sent spam", "should not
send email", "large mail origin", "residential ISP", "in the US",
"usually signs with DKIM", "has a strict SPF record", "uses MS
Exchange", ... etc.
postfix can check DNSBL (reject_rbl_client, ... etc). spamassassin can
check that and other stuff such as URIBL, SPF, DKIM, ... etc.
