Main Email problem


New member
I have a problem and I want to know if it happen only to me.
Any account after creation have a default mail, that the user is the same of the account name. (example only)

First time If I access by web mail, I can reach it.
If I configure the imap and try to connect to it, my entire web site and mail is not reachable for several days (I hope not months).
This is not absolute, I try to use NL proxy and from there I can see it.

It seems that some protection system avoid to use that email from imap or the email client wrong many time the user/password that the server for protection ban some ip range.

Does It happens to someone else?
Someone know why?
Someone know how to recover the ban IP?
