On a SQL Server 2005 machine, I have DBMail setup and correctly configured. I am able to use "Notify Operator" and EXEC msdb.dbo.sp_send_dbmail to queue emails.
But the problem is the queued mails never go through. I see 10 emails in the queue when I query
SELECT * FROM msdb.dbo.sysmail_unsentitems
But if I restart the SQL Server service, all mails go through and I receive emails in my inbox.
So far this is the only pattern I could find.
So my question is: is there a way to troubleshoot DBmail? I read some steps on MSDN, but they are not of much help. Any URLs to articles that could help are much appreciated.
