What about trouble with the DNSBL lists? I know when I changed my IP

We do get false positives from the blacklists on rare occasion, but
they're the same ones we got before postscreen.
Before postscreen, we had,
smtpd_recipient_restrictions =
permit_mynetworks,
...
reject_rbl_client psbl.surriel.com,
reject_rbl_client bl.spamcop.net,
reject_rbl_client zen.spamhaus.org,
reject_rbl_client b.barracudacentral.org,
permit
After postscreen, we have,
smtpd_recipient_restrictions =
permit_mynetworks,
...
permit
postscreen_dnsbl_sites =
psbl.surriel.com,
bl.spamcop.net,
zen.spamhaus.org,
b.barracudacentral.org
The two should be more or less equivalent considering that
postscreen_dnsbl_threshold = 1. (I should mention that you have to
register with barracuda before using their list.)
