"Or"? That's two different things.

If you don't know already: Even if you test all this, it is still
possible that

- the target mail account doesn't exist
- the sender's IP is filtered by the server so he'll reject
- the localpart has syntax errors (allowed chars in the localpart
are up to the server)
