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.
