not possible the wayit at the moment, however do the following.
1. go to fast hosts or 1 and 1 internet ( I use 1&1) and purchase a .co.uk domain name or other low price domain. (NOT .COM) for around £3 per year (in 2 year blocks total £6 aprox)
2. set the account to forward mail sent to domain address to you isp mail account
3. when you change isp in future just change mail forwarder on domain to new isp mail account.
Never change e-mail addresses again. Also get unlimmited addresses
i.e
spam@mydomain.co.uk for any on line forms you dont want mail from in future. set filters to just delete this addressed mail
Kids get own address. i.e
johnny@mydomain.co.uk mum@mydomain.co.uk etc etc. Outlook / Outlook express lets you set up multi mail accounts so everyone gets own account and mail soyou dontneed to have everyones mail in one inbox
For a few pounds. No hastle with losing mail. If transition between isp`s then forward to hotmail account.
Be warned. Do not action ridiculas letters telling you to renew at stupid cost or £90 £100 etc, just renew every 2 years in your account page in domain providers website usually automatically renewed for you anyway. Some "people" send letters to registered domain owners when due for renewal as a scam cos they know no better. Just chuck them in the bin. Read any letters from NOMINET as they are the domain name registration company.
