Hi Neetal,

Are you using email addresses or email aliases?

I had a similar problem before where I was using email aliases like 'Ronald San Juan' which was recognized by the mail server when the domain was up. Leter on, there were connection issues and the procedure (job actually) stopped working. There was no error message or anything. I replaced the email aliases with the email address (i.e. RonaldS@pcmall.com) and things were back to normal.

Hope this helps.
