Hi Len and other IMail Dudes, Len asked... >MSN / Imail speak SMTP, not registry. How would this registry value >be manifested in the SMTP dialog?
Beats me, Len. I was hoping you might know. :) Here's what I think might have happened, let me know if I'm way off-base. We have approx 1100 virtual hosts on our IMail server. About 100 of them were still using an official hostname in the format of imail.domain.com with a host alias of domain.com. The rest were using domain.com as the their official host and imail.domain.com as the alias. Naturally, using the latter format makes it a heck of a lot easier to scroll though such a huge list of domains when doing routine admin tasks on the mail server (using either IAdmin or the Web interface). About a month ago we decided to do some house cleaning and updated the 100 virtual hosts that were setup the old way. We followed the instructions posted in the KB on renaming an domains and we also cleaned up a few duplicate hostnames per the info in these KBs: http://support.ipswitch.com/kb/IM-20021119-DM02.htm http://support.ipswitch.com/kb/IM-20000512-DM01.htm http://support.ipswitch.com/kb/IM-19991007-DM01.htm Everything was working great for several weeks - then *bang*! MSN mail started piling up like crazy. Here are some of the log entries related to the SMTP_DELIV_FAILED snafu. The IPs 207.195.199.9, 207.195.199.12 and about a dozen others are bound to the NIC on the server. All the IP's that IMail uses have PTR records. 207.195.199.12 is IP that is assigned for the official host for the mail server. However it looks like smtp was somehow connecting to MSN on .9 and connecting to everyone else using .12. After the (Default) key value was cleared in the registry smtp connections to MSN started working again, the logs showed the expected IP address for connections to MSN. Weird, huh?
