I want to follow-up this thread with another questions pertaining to "Stack
Connect Fail" or "MX connect fail".
I've read the Ipswitch documents (IM-19981110) regarding this problem, but I
want to get more information to answers some
of my questions about the document.
1. Ipswitch's solution to correct the problem is to go to the
HKEY_LOCAL_MACHINE\SOFTWARE\IPSWITCH\IMAIL\DOMAINS
key and change the references to the internal IP address to the External
IP address.
This is what I see in my registry:
-Domain
- 209.233.174.11 <------------- This is the translated valid IP
addess of the machine, but the server is using a
private IP address. The firewall does
the translation from public to private address
- dmzff01.solanocounty.com <-----This is the fully qualified domain
name of the server.
Does this two entries have to be in the registry ? There are no references
to the private IP address that the
NIC card was binded to.
Thanks,
Jaime

Your host and host aliases information is in the registry. IMail is first
checking to see if the recipient is local.
