if you are on BB, i think that NTL do not need your password, try taking this off.

it should be in the SMTP section of the outgoing.

Thunderbird:
Tools > Account Settings > Outgoing Server (SMTP) >
Server name: smtp.ntlworld.com Port: 25 Default: 25
Untick use name and password & delete password


Outlook Express:
Tools > Accounts > Mail > Highlight your account > properties > Servers
Untick your remember password & delete your password
Apply & Ok

hope this gets your mail back.
