Nasty emails clogging up my pop3 boxes! RH7.3 Plesk7

Hi all,
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
Stu

This particular issue applies to Microsoft Outlook and Outlook Express - Tell the customers to switch to Pegasus or Eudora!!!!  - Only kidding!

I had an identical issue using Xmail as my server (http://www.xmailserver.org/). The key to solving this problem is the control of spam as has been identified by Glenn.

The solution that I used was a combination of spam-assassin and razor. Razor has now been integrated into spam assassin, so yo should find that merely implementing it solves the problem:

As 'dubious' emails can be forwarded to a different account for checking if required, I now use the Pegasus email client when administering this set up as it is immune to this 'lockup' problem:

Since installing this setup about a year ago, I have no lockups on client's email clients.

HTH:)
