Hi GUB, I feel you pain, but you are not alone,
I have had loads of problems over the last few weeks/months with .freemail, .co.uk and .com email accounts, went through with tech support changing server details etc that had worked perfectly for the last ten years, I get a few stable days then I too cannot receive again. I also noted that on the last occasion I could not get onto idnet's website which was the clue that I had been booted of the system completely as according to them I had too many failed logins, people sending me emails were having them bounce back as account unknown. Very helpful support, but not sure anything has improved long term. I have been with Idnet 11 years but I am starting think it is time to move on. I can understand the them not worrying too much with the free email addresses as part of your broadband package, but .co.uk cost extra a month.
