[lug] Postfix/spam reality check question...

[Chip Atkinson]

Greetings,

Recently I installed postfix with SPF and postgrey greylisting.  Before I
got greylisting going, it seemed that postfix was rejecting messages where
the "From " was different from the "Helo" and "From:".

Is this the default/expected behavior for postfix with 
smtpd_recipient_restrictions =
    reject_unlisted_recipient
    reject_unknown_sender_domain
    reject_unauth_destination
    check_policy_service inet:127.0.0.1:10023
    check_policy_service unix:private/spf

in main.cf?

Oh, check_policy_service inet:127.0.0.1:10023 is the greylist server.

Thanks in advance.

Chip
