[Mimedefang] 0x1f does not fulfill action requirements 0x3f

[The Searcher]

Hi,

Mimedefang starts without any problems, but when a mail arrives in the queue it's not processed by the milter and the syslog reports folowing:

MIMEDefang-2.44: st_optionneg[1090857776]: 
0x1f does not fulfill action requirements 0x3f

Below is a detailed log.

I'm running 
Red Hat 9
Sendmail 8.12.8
Spamassassin 2.64
Mcafee Virus Scan for Linux v4.32.0
Mimedefang 2.44

I followed the latest Mimedefang manual, with the exeption of chapter 4 "Install POP3, IMAP, and webmail services" (I skipped that one completely)

I installed all perl modules with the same version as the manual suggested, accept for Archive-Zip (I used 1.13 instead of 1.11)

Has anyone got a sugestion?

TIA,
Remon
