So, just to summarize all the changes I need to make:
1. Situation before the changes:
There is the Master (at "mail.dom1.org", serving mail for the
domains "dom1.org" and "dom2.org") and the Backup system (at
"mail.other.org").
The Name Server zones list the following MX records:
for the "dom1.org" zone:
dom1.org. MX 10 mail.dom1.org.
for the "dom2.org" zone:
dom2.org. MX 10 mail.dom1.org.
2. On the Backup system, I then just add the following lines in the
SIMS' Router field:
dom1.org = dom1.org.smtp
dom2.org = dom2.org.smtp
3. On the Master, if I use RBL (blacklists), I could add the IP
number of "mail.other.org" to SIMS' SMTP Client Hosts list, in
order to avoid RBL checking when the Backup system tries to
send mail to the Master. This is optional, though, and just
helps performance a tiny bit.
4. I add the following MX records to my domain zone files:
for the "dom1.org" zone:
dom1.org. MX 20 mail.other.org.
for the "dom2.org" zone:
dom2.org. MX 20 mail.other.org.
Is this all correct? Did I miss something?
One more question, though: Where is this "dom1.org = dom1.org.smtp"
thing documented? I could not find it in the SIMS online docs.
