Here's the current setup:
mail.domain-A: domain A
mail.domain-B: domain B,C,D
New Server C is set up as mail.domain-A with all the domains added via
vqadmin. Everything seems to be working fine, I can log into all the domains
and send from accounts on them with no problem. My testing hits a snag when I
try to test incoming email.
When I swap the new server out with server A on isp A, it's business as
usual. I send and receive all files related to domain A with no trouble. When I
try swapping out with server B on isp B though, I get nothing. I can send
emails no problem, but it doesn't seem to be receiving anything sent to domains
B,C or D.
Can anyone tell me why this is happening? I'd like to know that this is going
to work properly before I can point all my domains to one IP and swap out both
old servers for the new one. We rely highly on email so I can't afford much
downtime at all if something goes wrong and I have to point a domain back to
the original IP to set things back to the way they were. Any help will be
greatly appreciated.
When you put the server on connection A everything works. Why do you move it to
B? Why not just change your DNS to point domains B, C, and D to IP address A?
Did you change the IP address when you put the server on network B? What does
your rcpthosts file look like? Did you make any changes to your tcp.smtp file?
Multiple domains do work. I have a server with 161 domains and 2800 users on it
with no major modifications made that differ from a standard install.
I move it to B to make sure that we can receive emails for B, C and D as well.
I change the IP address and ip address in /etc/hosts of the new machine to
either server A or B when I swap them out, this is a straight switch so that I
can check if they're receiving emails ok.
My rcpthosts shows:
mail.domain-A.com
domain-A.com
domain-B.com
domain-C.com
domain-D.com
I didn't make any changes to the tcp.smtp file. The reason why I don't point
just point B,C,D to A's Ip address is because it would make more sense to only
have to move one IP rather than 3 and also, the other ip is on the better
connection which we'll be keeping after consolidation.
By all rights, shouldn't swapping the new mail server into B work outright? is
there any reason that it shouldn't?
