Yeah well, I 've got around 50 emails outgoing and around 30 incoming. I am not sure what the problem is, but I guess you 're right.
Anyway, I think I may try with another email as well, but the only one which I think I could use has even less emails.
Well, if privacy is not a big concern for you then you may use Gmail. I've reported all of the domains via Gmail and all of my mails were sent within seconds. So here gmail works pretty well.
