[BlueOnyx:19503] SMTP connection problem

[Lewis Gardner]

Greetings!

We moved a BlueOnyx 5208R from one IP address to another and now it 
appears that SMTP will not accept a connection from the primary email 
users. The difference is that the primary senders are now on the same 
subnet. Previously they were on different subnets.

Previously 7x.1x3.6.128/28
Now        7x.1x2.59.64/28

The primary email users are on 7x.1x2.59.66 and the BlueOnyx 5208R is on 
7x.1x2.59.69. Sending mail works perfectly from anywhere except the 
network the primary email users are on.

Am I crazy? Trying to telnet in on port 25 from 7x.142.59.66 gives 
either a connection refused or times out. Works fine from anyplace else.

Any help would be greatly appreciated!
