Tech Tip: Click here to run a free scan for Windows Errors and optimize PC performance

Need to have the new domain & old domain to co-exist on one exchange server
5.5 (ip addr= 10.0.100.5); but the mail server is rejecting mail from old
domain getting 550 Relaying is Prohibited when I telnet -mail server config
problem or not? IMS connector is configured to accept both domains -MX & A
records needed?

Mark,

If I understand this correctly, you are changing from:

olddomain.com IN A 10.0.100.5
olddomain.com IN MX 10 mail.olddomain.com
mail.olddomain.com IN A 65.219.171.135

to:

newdomain.com IN A 10.0.100.5
newdomain.com IN MX 10 mail.newdomain.com
mail.newdomain.com IN A 10.0.100.5

Is this correct?

What emails are being rejected? Also, what is the PTR record for
10.0.100.5?

From the config below, it looks like you have mail.olddomain.com configured
as a mail exchanger for the sub-domain: mail.newdomain.com. Is this what
you want?

Having trouble with dual smtp domain records; only the new host domain can
use email while existing host email is rejected from new domain; here are
the
records listed in new domain: (BTW, running on NT4 server)
newdomain.com-
newdomain.com MX [10] mail.newdomain.com
mail A 10.0.100.5
mail MX [10] mail.olddomain.com
mail A 65.219.171.135 (external
mail.olddomain.com address)

BTW- newdomain & oldomain share the same internal ip of 10.0.100.5

This is the last thorn on my side to complete this changeover...thx
