Yeah, back in the day, when we had version 6, we switched all our customers' shared Imail servers to require SMTP authentication
(of course we had tested everything with success beforehand, and sent all customers a letter explaining the need for SMTP authentication and how to configure their e-mail programs) Back then we had I think 8 or 9 servers with ~1,000 domains on each (with at least 5 users on each domain) It was a big OUCH. We were bombarded with customer support calls. Despite everything working well in tests, it turned out to not always work in practice. Often we had to restart the SMTP service - after running for a while it just did not want to authenticate anyone anymore. Upgrading to version 7.x helped a lot. But some customers are not able to authenticate to this day. And we can't figure out why. Customers who use Outlook Express or Outlook or Entourage for Mac are not able to authenticate to this day. -----Original Message----- From: Allen Thompson [mailto:[EMAIL PROTECTED]] Sent: Tuesday, January 21, 2003 10:36 AM To: [EMAIL PROTECTED] Subject: [IMail Forum] SMTP AUTH This is driving me nuts..... I have recently set up our servers so that users must now authenticate when sending mail - I am hosting for about 50 domains in all. No easy job as I had to talk several of them through setting up the authentication process on their mail clients. However, I am now left with 2 users out of about 250 who cannot authenticate whatever I try. They are both using M$ Outlook Express ( newer versions ). The server is set up for "No Mail Relay" and "Disable SMTP AUTH" is not ticked "Disable SMTP VRFY" is ticked. Has anyone been here before have ANY ideas as to what is happening here? and what's more to the point why it doesn't work.
