Hi List,<br>
<br>
I have this conundrum which I am hoping the experts on here will
help me resolve. :) <br>
<br>
How do I tell mailscanner not to rescan an email that it had already
scanned? <br>
<br>
I have a small server set up with mailscanner, spamassassin, etc.
whose sole purpose is to process the inbound and outbound emails for
a separate mail server. The mail flows well between the mail server
and the mailscanner server. The issue I have is with 'forwarders',
which are, as all of you will know, essentially an email address
that is set up to forward incoming emails to another email address.
<br>
<br>
Briefly, an incoming email for a 'forwarder' first hits the
mailscanner server (being the primary mx), it gets processed for
spam and viruses and then handed to the mail server. The mail server
sees that the local address is not an email account but a
'forwarder', so it sends the email back to the mailscanner server
for processing and distribution. That is fine. However, MailScanner
treats the email on the second pass as completely 'new' and scans it
for spam and viruses again, <font face="Verdana, Arial, Helvetica">which is unneeded and causes unwanted resource usage.<br>
<br>
<font>Is it possible to tell mailscanner not to scan
twice<font> by having it evaluate the headers so it
could see that it<font> is dealing with an email
which it had already scanned</font>? I couldn't find any
options<font> for th<font>is in the .con<font>f</font> file. The MTA on both servers is Exim,
in case that may be relevant.</font><br>
<br>
<font>Regards,</font><br>
</font></font></font></font><br>
