I am currently providing web hosting on a RH7.3 box running Plesk 7.0.2 Control Panel software.
The problem I currently face relates to qmail. I am receiving occasional emails from spammers which have incomplete headers such as date/time incorrect or senders name is blank. This is causing customers email clients to "Lock" on collection of emails. If we then use webmail to clear the offending item all is well.
How can I set a filter on qmail to basically trash these incomplete emails or forward them to a global trash box?
Cheers in advance
