I beleive it is worth mentioning that, both BT and NTL supply these services as is and do not offer any kind of SLA, if you want reliable email service then register a domain name and use that to send and receive email, NTL and BT's mailservers get so busy that stuf will get lost in the ether only to return 5 days later, or heaven forbid never turn up.
My company ofers email only domain accounts pm me for details
