Outlook can't tell wheter the destination addess exists or not. But Outlook should tell the user about any 5xx during SMTP communication.

Did you send this message to multiple recipients? Generally, if you act as a submission server (and if you are sure about the identity of the sender), you should accept all messages first, and then generate bounces to the sender, if you encounter any failing recipients. This is more comfortable for the sender - getting a bounce with a list of failed addresses. Otherwise you just get a popup (if at all) about some failure. Imagine a list of 1000 recipients, and your Exim rejects just some of these. Depending on the client it is almost impossible to sort out the failing address. Of course, no direct solution to your problem, but OTH I'd say, Outlook can't be so stupid as you write (even it's an MS product), I'd try the find the error in some other place… -- Heiko :: dresden : linux : SCHLITTERMANN.de GPG Key 48D0359B : 3061 CFBF 2D88 F034 E8D2 7E92 EE4E AC98 48D0 359B
