Panel Fully correctly configured - But not sending emails

[chaosnature]

I really like this tool; however, I have not been able to get it to work for me yet.

I send an email test, and it does not deliver even though it says sent.

Also, it seems all emails I sent from my test list seem to bounce immediately, even though they are my own emails.

I would appreciate any assistance in solving this issue; I think it might be a very little one.

regards
