multiple domain

Post by wclune » 25 Sep 2018 20:11

Hi newbie sort of question.... I have for many years been running a roaring penguin canit appliance, but since their sale to appriver it is clear we cant afford that any longer. I house email for some friends and family domains, a few hobby club emails with a handful of commercial "customers" making it worth doing.... is EFA capable of being an MX server for multiple domains, with each having its own "stream"?

The short answer is yes, it supports as many domains as you want to front.

EFA is mailgateway, it not a mail server for accounts, I use it to front an Microsoft exchange environment, so you would also a server behind for IMAP and POP accounts and webmail , eg https://www.dovecot.org/

However see viewtopic.php?f=8&t=3142 regarding the possibility of an "All in one mailserver"

Thanks! This is just to replace the MX server which is in front of a pop/imap and 2 exchanges.
I'll dig a bit deeper thanks.

in etc/postfix/main.cf add you domains to line

relay_domains = domain1.com, domain2.com, domain3.com

in etc/postfix/transport

domain1.com smtp:[x.x.x.x]
domain2.com smtp:[x.x.x.x]
domain3.com smtp:[x.x.x.x]

where x.x.x.x is your exchnage server

remember to do "postmap /etc/postfix/transport"
