It wasn't just the email side, I was getting 42.6 kbps on dialup modem, with 2,452,037 bytes sent and 7, 347,681 bytes recieved (Tiscali isp) but no surfing etc. Pages were taking ages to part load but not completing. I don't think it was pc. Anyway, it's ok today. Thanks for responses.
The Tiscali connection seemed to be working okay over the weekend,excluding the email problems.I have been having emails problems for about a week now.Getting them in,but not able to sent all out.Tiscali technical have informed me, that it is a 'third party'problem.
