I'm in the midst of a server platform swap and part of it is moving from a
sendmail/mailscanner environment to a postfix/mailscanner system.  Of
course, everything has been updated to the most recent versions for Centos
6.4 from fairly ancient versionsŠ

I'm seeing two quirks that are annoying but not impacting delivery:

For some reason, even though "sign clean messages" is set to yes and I
verified the locations of the inline text, it never shows up in delivered
I'm getting regular messages from MailScanner complaining about Problem

As I said, these don't seem to be interfering with email, but I can't find
anything in the logs that point me to a solution.  Any suggestions from the

Centos 6.4
Postfix 2.6.6
Mailscanner info from Mainscanner‹lint

> MailScanner --lint

Checking version numbers...
Version number in MailScanner.conf (4.84.5) is correct.

Your envelope_sender_header in spam.assassin.prefs.conf is correct.
MailScanner setting GID to  (89)
MailScanner setting UID to  (89)

Checking for SpamAssassin errors (if you use it)...
Using SpamAssassin results cache
Connected to SpamAssassin cache database
SpamAssassin reported no errors.
I have found clamd scanners installed, and will use them all by default.
Connected to Processing Attempts Database
Created Processing Attempts Database successfully
There are 7 messages in the Processing Attempts Database
Using locktype = posix
MailScanner.conf says "Virus Scanners = auto"
Found these virus scanners installed: clamd
Filename Checks: Windows/DOS Executable (1
Other Checks: Found 1 problems
Virus and Content Scanning: Starting
Clamd::INFECTED::Eicar-Test-Signature :: ./1/
Clamd::INFECTED:: Eicar-Test-Signature :: ./1/
Virus Scanning: Clamd found 2 infections
Infected message 1 came from
Virus Scanning: Found 2 viruses
Virus Scanner test reports:
Clamd said " was infected: Eicar-Test-Signature"

If any of your virus scanners (clamd)
are not listed there, you should check that they are installed correctly
and that MailScanner is finding them correctly via its virus.scanners.conf.
