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.
I know this, but to be sure ...
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.
Like I said, the mailserver at work, and at home, has to use the ISP's relay server. That's because outgoing port 25 is blocked in the "domain" of the ISP. With domain I mean all IP's from the ISP's. On one side I can understand, this limits the effects of "bots" sending from those IP's. But for me, at this moment, it's a pain.
Ah, I see, I missed that earlier, sorry. Perhaps use port 587 on your home mailserver and have your backup server send the mails to that? -- Per Jessen, Zürich (9.9°C) http://www.dns24.ch/ - free dynamic DNS, made in Switzerland. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
