I had a very serious problem. After several successful test installations on production servers, we performed a final "clean" installation in our lab. For security reasons, the lab is on a private, non-routable subnet, with DHCP providing temporary IPs, etc. Installation went as expected, through Windows 2000, IMail, Declude JunkMail & Virus, and KillerWebMail.
Then, we moved the new IMail server into production. The temporary DHCP-supplied addresses were replaced by static addresses. IMail's SMTP service was updated to use the new DNS servers. The server immediately had "issues." The first symptom we detected was that Declude JunkMail was failing to resolve any of its DNS-based tests (ip4r, etc.). When told that Declude obtains its DNS server information directly from IMail, I began looking for references to the temporary DHCP-supplied IP address or DNS servers. The only reference I found was in the registry. IMail had a virtual server with the old address. I deleted the entry (doh!) and things REALLY went to hell. Even after restoring the entry, it was too late. Mail was failing all over the place. Still in the production environment, I removed and re-installed IMail, Declude and KillerWebMail. The problems disappeared. I must conclude that IMail does indeed have problems when changing the server's IP address. That was the ONLY step different in this particular installation from the others. Mine was an absolute clean installation and the problem should be easily replicatable. Combine this issue with IMail's hoggish consumption of every IP address on a multi-homed server. This is not very elegant. Had I been able to tell IMail which IPs to use, I might have had success in kicking out the temporary DHCP address. But, alas, no. I would be very interested to know the root of this problem and any workarounds that might have saved me (from botching my own registry). Heaven forbid, we might move the server again.
