Hi,
spamcop.net is blocking mailservers when bounces arrived at spamtraps. This means, that the behaviour of qmail-ldap will result in a listing on spamcop.net.
We use RCPTCHECK but user over quota bounces will go out and in worste case to the spamtraps of spamcop.net. When this happen, the mailserver is blacklisted. Forged from addresses in spam/virus mails are today the normal way.
So what to do? My oppinion is a patch similar to RCPTCHECK which check the quota and send a 553 during the smtp connection. Any ideas why this is not a good idea? Any other suggestions?
