All,

Could someone try to explain why postfix is a better choice for an SMTP gateway then a recent
version of sendmail ? Since we are using sendmail on all other machine in the organization, why
would I choose postfix on the SMTP gateway ?

Thanks
Daniel Nilsson

So I would I now... ;)) Do you think the solution mentioned in the
German Linux-Magazin
in June this year by Micheal Wiesmer is favourable?!?


You mean http://www.linux-magazin.de/ausgabe/2001/06/Amavis/amavis.html,
yes? :-) (it's a very well written article, btw :))

Well, amavis-perl/amavisd works very well with postfix (for obvious
reasons, as Lars and myself use only/mainly postfix). amavisd is faster,
as forking a child is faster than creating a new perl process for every mail.
For speed reasons I'd suggest to use a virus scanning daemon, such as
Kaspersky kavdaemon or Sophie for Sophos Sweep. Please see the amavis-user
ML archive for details here.

Alternatives are i.e. avcheck, which was "designed" for use with
kavdaemon or H+BEDV AntiVir, Trend InterScan VirusWall or Sophos new
SMTP-scanner (the latter ones can all be configured to use postfix
content_filter method, i.e. listening on port 10025 to receive the mails
from postfix and sending non-infected mails back to to postfix via port
10026). But I haven't tried out the new Sophos product with postfix yet.

HTH

best regards,
