Hi All,
The question on the following is: how can I enable MailScanner filtering
for both incoming and outgoing emails, without having double scans at
incoming emails and none at outgoing?
I have setup the following:
Incoming emails are delivered with SMTP to server -> then forwarded to
MailScanner -> then to the filter script -> then to UUCP -> then to
alternate postfix server.
The Mailscanner is invoked with header_checks through main.cf:
header_checks = regexp:/etc/postfix/header_checks
cat /etc/postfix/header_checks
/^Received:/ HOLD
The filter is invoked with smtpd options from master.cf, as below:
smtp inet n - - - - smtpd
-o content_filter=filter:dummy
The filter does a basic check and increases a counter, then delivers back
with local delivery (pickup) the email.
On this step, the pickup triggers again the MailScanner, which is not
needed since the MailScanner already did his job.
to avoid this I disabled header_checks at pickup with following option at
master.cf:
pickup fifo n - - 60 1 pickup
-o receive_override_options=no_header_body_checks
And this resolves the issue for incoming emails.
For outgoing emails though, which come from UUCP (delivered locally through
pickup) I do not have MailScanner scanning if I disable the header checks
at pickup.
What is your suggestion to have Mailscanner scan once (and not twice) at
incoming and once at outgoing (and not none) emails?
Hope hat make sense.
Thanx,
Alex
