MailScanner does not notify virus senders

[Roel Schouten]

Hello,

My installation of MailScanner does not notify senders of viruses even
though I told it to do so.
Otherwise my installation works fine (it both filters spam & virus).

I use MailScanner 4.37.7 on a RedHat Enterprise 3 running kernel 2.4.21-27
with PostFix 2.0.16 as MTA.
Moreover, I use ClamAV 0.80 and SpamAssassin 3.0.2

I use the following settings in /etc/MailScanner/MailScanner.conf (I only
included the ones, I believe to be relevant):

Run As User = postfix
Run As Group = postfix
Incoming Queue Dir = /var/spool/postfix/hold
Outgoing Queue Dir = /var/spool/postfix/incoming
MTA = postfix
Sendmail = /usr/sbin/sendmail
Virus Scanners = clamavmodule
Quarantine Infections = no
Quarantine Silent Viruses = no
Notify Senders = yes
Notify Senders Of Viruses = yes

To test the virus scanning functionality, I use the EICAR test virus.
The log does not show any errors:
Jan 12 16:46:35 mail MailScanner[15031]: New Batch: Scanning 1 messages, 719

Jan 12 16:46:36 mail MailScanner[15031]: Virus Scanning: Found 1 viruses


MailScanner is able to send notifications to the system administrator by
setting "Send Notices = yes", so that works.
It also possible to use /usr/sbin/sendmail (Postfix' version of it) to send
mails to external addresses from the command line.

Any clue? Thanks!
