Cool ISPCONFIG Anti-Spam filter not causing problems for user account

Hello group,

I have an ISPCONFIG box running on CentOS 5.0. ISPCONFIG has been running like a top up until recently. The problem is that one of my user accounts is blocking all or most of my incoming email due to the spam filter or rather spamassasin. Under "Spam Filter and AntiVirus" for the user account I have:

Spam Filter: checked
Spam Hits: 5.0
ReWrite Subject: checked
Subject: ***SPAM***
Use URIBL: checked

These are the exact same settings as most of my other accounts however inbound email is being blocked all of a sudden just on one account. I have had several persons recently inform me that they cannot get mail through and are getting errors. The only way to allow mail is to "uncheck" Spam Filter which I have done so that I can communicate with the world on this account in question.

I downloaded and installed all of the latest CentOs updates and also upgraded to the latest ISPCONFIG from 2.2.18 to 2.2.23 in hopes that this would be resolved but no luck. What is going on here. Very Strange. Somehow the spam filter is getting way too strict for this user. I am not sure exactly how I should approach resolving this issue. It appears that a "lockfile" cannot be created for this user.

Here is the actual email (minus the real servernames) that got bounced back.

retest with new ispconfig



myserver.com is the server in question that is not creating the lock file for this one user. It had been up until about a week ago then all of a sudden things stopped working. My other email accounts are configured exactly the same and have no problems with spam filter enabled for the user. Again, the only way I can get email inbound to my "art@myserver.com" right now is by unchecking or rather deactivating the spam filter.

Any help is welcome and thanks in advance for your reply.
