Hello,
I saw this configuration in our master.cf as follows.
What's the difference between the option "smtpd_relay_restrictions" and
"smtpd_recipient_restrictions"? In my opinion they both mean the sender
must pass the smtp auth. Thanks.
smtps inet n - y - - sm
In my experience, I have Hotmail, Freenet.de forwarded to gmail. Both
hotmail and freenet have no SRS for their forwarding emails.
But gmail never classifies their forwarded emails as spam (unless they are
really the spam) until they have correct DKIM signs.
Regards.

Gmail/fastmail rely more on DKIM than SPF.
And, some huge providers (such as Microsoft, Mail.ru) have no SRS enabled
for their forwarding mails.
In my experience, don't rely too much on SPF settings, either for incoming
email or for outgoing mail.

I have been using spamhaus, spamcop, sorbs as the RBL providers for
antispam.
But some of the customers speak to me about the FP issues caused by RBL.
Do you think the three RBL above are reliable in a practical system?
Thanks
