I have recently setup SMTP proxy with authentication for my users. ONE of my remote users cannot send email. All the settings on his machine are indentical to my machine at home that I use regularly to send/receive email via proxy; yet he gets errors when trying to send. ( Sending' reported error (0x800C8105) : 'Unknown Error 0x800C8105' )
The only difference between our machines is that he has Norton 2005 and I have Norton 2004. Both have outgoing mail scanning turned off, yet his attempts to send mail fail. If I deselect use SSL on the outgoing server, the error says Relay not permitted to external addresses and sends mail to internal users fine. When 'use SSL' is checked it prompts me for his password over and over...like it's getting the wrong one. However since SMTP authenticates against my internal LDAP server, the username and password are the same for incoming and outgoing and he receives mail fine.
Any ideas are appreciated.

More news on this issue. I set this user and this user only up with local authentication instead of LDAP auth like all my other users and it works for him. Why would LDAP authentication fail for only this one user? He has SMTP enabled under his user definition.
