I use a MAC and e-mails will come onto to my desktop without a problem for days, then suddenly my BT mail needs verification of username and password, which is rejected. This rejected process can last for days. After continually phoning BT, they inform me that I should just use the online Yahoo page to collect my mail. Thank you BT - problem solved 😞
Sadly, I have reached the end of my tether with BT's yahool mail. This has been a problem since the middle of 2011 for me. It is now fast approaching a year later and BT have still not got their act together in solving this issue. Go and do a google search on BT Yahoo mail problems and you will be shocked to see how long this problem has been going on and nobody seems to be coming out with a permanent solution. This problem is being discussed on countless forums. BT Wake Up!
I am now about to e-mail my mailing list to ask them to stop using my btinternet address and to use my alternative and more reliable e-mail address.
