I run a server hosting several domains (a.com, b.com, c.com) and have up to now used Postfix' virtual domain capabilites to accept and forward mail in this fashion:

/etc/postfix/virtual:
Code:
# incoming for   forward to
info@a.com       customer-a@somehost.net
info@b.com       customer-b@somehost.com
info@c.com       customer-c@somehost.org


So there was no local delivery at all, just forwarding of certain well-known addresses. Also, there are no user accounts for a, b or c on the server.

I now happen to reinstall the server from scratch and wonder if there is a more lightweight, yet secure, alternative to Postfix for this kind of work.

Any pointers?

Thanks!

You might try esmtp or nullmailer but personally I would just stay with postfix if it works.

Well you don't really give many hints as to what you want.

If you are just relaying mail then I suggest changing the MX records for those domains to deliver direct. Why bother creating a pinch point or a single point of failure?

If you are scanning for spam n viruses then I can personally recommend Exim + Spam Assassin + ClamAV. If you want a hand with that I can send some examples or you can have a go and then request help for specific points.

I have one customer with 10 miliion separate IPs per week trying to mail harvest them. They have a 2.5Mbs-1 ADSL line and the mail host is a dinky Dell box with 1Gb RAM, I have the logging going to MySQL as well as various text files via rsyslog and it hardly breaks a sweat. Is that light weight enough? In general it is down to configuration and not system choice that defines utilization for this sort of thing.

Cheers

If you've been happy with Postfix then stick with it. There isn't much I'd run that's simpler and Postfix has a pretty good security record after a couple of early missteps. Also it's flexible enough that if you need more logging or custom changes on the fly you've got those options.
