Look at a raw "encrypted" message.
The code (sub EncryptionStatus in module
/usr/lib/MailScanner/MailScanner/SweepContent.pm) seems very
It looks at the Content-Type: of the message and all its sub-parts for a
match on the pattern /\/encrypted/i. If any header matches, it says the
message is encrypted, otherwise not.
Thus, it seems that your encrypted messages do not contain any
or similar headers.
