Blacklisted by what?  What does your BLACKLISTS= setting look like in
/etc/courier/esmtpd?

The best way would be to determine what blacklist is braindead enough
to block Google and stop using it.  We all know that some spam is sent
out by Hotmail, GMail and Yahoo Mail servers but a *lot* of legit mail
from users comes from these big three also, I recommend you use a
blacklist service like Spamhaus that is much more cautious about
blacklisting an IP address.  I've used them for nearly 4 years now and
have 0 false positives to report.  I rely on local filtering
(SpamAssassin) to catch spam from IPs that Spamhaus was to
conservative to block.
