Postby Redbit » Wed Jul 10, 2019 3:32 pm

Hi, I've a Multi Server installation with a Proxy server with its MTA, a Mailbox server with LDAP and 4 MTA server.
It's possible to use in round robin all four MTA server not only via web client, but always?
Thank you for help.

Hello.

Easy round-robin is by using DNS.
So create a round-robin record in your DNS (out and/or in) then point your clients (and incoming mails) to this record.
However, with that solution, you'll get all the usual round-robin issues: if a server goes don't it's stays in the pool, load per server will be linked to DNS answers (not emails amount not current load), etc.

If you want a "real" and clean solution, have a look at a reverse-proxy such as HAproxy (and it's "send-proxy" feature that postscreen knows how to use).
