Hi Jon- Maybe this ground was covered by others, by you seem still be in "SOS" mode.
What about DNS? There is an old issue with IMail and DNS resolvers. The following configuration solves the problem: Your IMail box should have the Microsoft DNS Server service installed. The default installation is as a caching server, which is exactly what you need. The Network | TCP/IP params should specify high speed DNS resolvers provided by your access provider, NOT your local DNS servers, which should be set for no recursion. The IMail SMTP DNS server should be set to 127.0.0.1 The old IMail docs say you can use multiple resolvers by specifying ip addresses separated by spaces in the IMail SMTP property sheet. In fact, this has never worked. Microsoft does a competent job of resolving addresses, and the reference to 127.0.0.1 simply tells IMail to rely on the Microsoft DNS service. -Dave Doherty Skywaves, Inc. ---------- Original Message ---------------------------------- From: "Jon" <[EMAIL PROTECTED]> Reply-To: [email protected] Date: Wed, 6 Dec 2006 21:25:31 -0500 >Hi all, > >I tried running ASSP again but it didn't matter.
