Any 'Net mail' account will do as you just have to be able to get to the site. you could try BT's Talk21 net mail basic account which is free. You just log on to your mail (Talk21) account at click here on any computer connected to the WWW and read/send mails as you need. I believe MSN mail & holtmail are simular.
My som uses talk21 mail in this way in Spain & the UAE without any problems.
