Hi cag, I've only just found out that NTL are having problems with their servers, particularly after 5.00pm.
I can send e-mails all the day but come tea-time and it either takes a very long time to upload or it keeps asking for your username and password.
Their Correct Connect program which everybody seems to dislike can tell you that your computer is OK, the connection is OK but their applications (servers) are not OK.
i spent an hour the other night checking and re-checking my password and other details to no avail.
I also believe (from the FE) that AOL have a similar problem with a too vicious anti-spam program which they installed and this causes bounced e-mails.
We'll just have to wait until they sort themselves out, I guess!
