I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Check the mail server logs and see what kind of address smrt is.

If it was rejected by the recipient, then they may have restrictions on emails to that address. This is something they will need to look into. If you confirmed that the email is valid, then i will toss that back to the recipient side.

I advise you send a test mail from gmail and check the result.

Your issue's clear, you need to find out to whom this person needs to report before sending out specific emails. But to me, it's not because of a moderator. If somebody has to check your email you shouldn't receive any bounce back email until the manager approved it and let the email go.

To me, it's another restriction. You need to check and do some testing.
