Network problem

[Yanni]

My network settings were working fine, now i get these errors out of the blue!

server: passed
connection: failed
sockets: passed
communications: failed
authorisation: failed
message: Connection refused


What am I doing wrong? I use exactly the same settings inside Mozilla Thunderbird and have no problems whatsoever. Tried changed the SMTP server to "auth.smtp.1and1.co.uk" with or without user nmae an password without success.

These are my network settings:
