Scheduled agent - email address

I have a scheduled agent set to send an email when a new document is added to a discussion database.

The agent runs, but the mail gets stuck in the mail.box. The agent does work and the mail is processed if ran manually. Regular email being sent back and forth works fine.

I don’t know if it has anything to do with the fact that the @smtp is added to the end of the address. ex: user/company@company

any ideas?
