Either your username and password is set up incorrectly in Email options, or the email account has otherwise been locked out due to failed log in attempts from other locations.

You would need to contact whoever runs the mail server to unblock it and hopefully they can explain where the failed login attempts came from.

The Username and password has not been changed since they were created. Could it be that someone tries to access it? what has this website got to do with this? bl.websitewelcome.com!! Any idea?

They seem to provide a real time blacklist service -- a service that can be called up to check if a specific domain is blacklisted for any reason. It seems as though your email domain might be on that blacklist for the reasons given.

You will need to contact your mail server administrators. It would be them feeding information to the black list service, and them who will be able to unblock you and hopefully tell you what happened.

we run microsoft's smtp service on localhost so there's no username and password.
