dovecot_plain authenticator failed

Hi, I have problem with my account email, I can send email and receive, but after 2 days my hosting server blocked my IP: this is the message
<!!! --- Not sure why it shows that within the same SECOND, you are attempting to login to both Imap AND pop3. -!!! --->
I don't know how to figure out (user and password is ok)

I'd suggest discussing this issue with your hosting provider further. It sounds as though you may have multiple email clients connected but they'd have more relevant information.
