I have an SBS 2003 server running a remote backup client which dumps backups to an off site facility. The backup client has an email notification option which I have enabled and configured to use the administrators credentials for authentication to the mail server (itself). The problem is the email keeps failing. The application throw a generic saying the " Email: firstname.lastname@example.org was unsuccessful". The log in the event viewer looks like this if it's any help:
This is an SMTP protocol log for virtual server ID 1, connection #15277. The client at "192.168.1.10" sent a "ehlo" command, and the SMTP server responded with "250-realsbs01.realcalgary.ca Hello [192.168.1.10] 250-TURN 250-SIZE 250-ETRN 250-PIPELINING 250-DSN 250-ENHANCEDSTATUSCODES 250-8bitmime 250-BINARYMIME 250-CHUNKING 250-VRFY 250-X-EXPS GSSAPI NTLM LOGIN 250-X-EXPS=LOGIN 250-AUTH GSSAPI NTLM LOGIN 250-AUTH=LOGIN 250-X-LINK2STATE 250-XEXCH50 250 OK ". The full command sent was "ehlo realsbs01". This is an informational event and does not indicate an error.
I have used telnet from the server itself to test using the same email addresses and everything looks fine but the message never seems to hit the queueu although telnet says the message has been queued. Anyone have any thoughts on this? I assumed the connector would accept email from an application if it is authenticating but this does not seem to be the case.
