So... I seem to have the same problem on one of my servers. Thing is that the server had Kasperky ages ago, but it was uninstalled after a few days. I use Dr. Web now (DrWeb 4.33.0.10050, last update: 16.01.2007, additional license for it) but sometimes the SMTP queue just hangs.
To temporarily fix it, I only have to restart the Plesk Management Service, not the whole server or any MailEanble services. I'm running the latest MailEanble version (1.981) as all the previous version have security vulnerabilities on the POP3 service, however, I think the problem is caused by Plesk, not by the mail server.
Also, the MTA pickup event in MailEanble is enabled, but the 'Program to execute on mail file' is empty. Is that normal?
Also, most of the the entries in
C:\PROGRA~1\SWsoft\Plesk\MAILSE~1\MAILEN~1\LOGGING\MTA\MTA-Debug-070117.log are like this:
01/17/07 00:17:39 Pre Pickup Event executing: 00C84B694FFF43F898F7DE98DBA58027.MAI SMTP
01/17/07 00:17:39 Pickup Event could not find path to executable (2): ( 00C84B694FFF43F898F7DE98DBA58027.MAI SMTP)
01/17/07 00:17:39 ME-MTA-022: Antivirus and other filters were bypassed because you are not licensed to use them. Please run your diagnostic report for more information.
As far as I see in Plesk, my license is OK:
Key number PLSK.xxxxxxxx.xxxx
Next license key update Feb 26, 2007
Key expiration date Mar 8, 2007
.......................
Ability to use Spam Filter On
Ability to use Antivirus On
and the additional license for Dr. Web:
Key number PLSK.xxxxxxxx.xxxx
Key name antivir-drweb-4
Next license key update June 2, 2007
Expiration date June 7, 2007
By checking further the MTA log, I noticed the exact time the SMTP queue hung up:

As you can see, between 03:15:31 and 04:10:54 no email was processed by the MTA agent (until I manually restarted the Plesk Management service).
Any ideas? I would really like to keep Dr. Web as an AV solution (since I payed $200 for it), but as a last resort, I can switch to ClamWin, as it's running fine on the other servers I have (there is a bit of load of the server when it scans, but I guess I can live with that).
Also, I'd like this fixed now, not in Q2'2007 when SWsoft "plans to improve it".
