I am unable to send emails from sharepoint, i noticed that there is a problem with my smtp server settings. I am able to send emails from .net code using smtpclient but with basic authentication using NetworkCredential class only , if i dont use basic authentication then emails are stucked in queue folder.
All alerts/notifications based emails from sharepoint are stucked in queue folder.
I gave my server IP address in outgoing email settings in central administration in moss2007.
and i gave basic authentication in smtp server, but not able to send emails, got stucked in queue.
Please help me on this issue.
