Hi,
My internet connection at home is broken. I was trying to set up a backup mailserver at work.
A backup mailserver is most often superfluous. Any mailserver trying to contact your home mailserver will retry, usually up to 5 days before returning a mail as undeliverable.
But thinking about it I fear it's impossible. Please comment :
In an MX-record of my home-domain I point a secondary address to the mailserver at work. The mailserver at work is configured to accept mail as relay for my home-domain. Unfortunately, my mailserver at work is forced to use the relay-server of my ISP. So when my werk-server accepts mail for my home-domain, it is able send this to the ISP-relay. The ISP-relay can't send it to my home-server so it sends this the my work-server etc. An endless loop.
Am I right in this analysis ? How to solve this ?
Your backup server at work should be configured to only try to deliver to your home-server, not to use the MX. In postfix, you can do this with a transport map for instance. -- Per Jessen, Zürich (8.5°C) http://www.hostsuisse.com/ - dedicated server rental in Switzerland. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
