Over the past few weeks I have been aware that some e-mails are not arriving (mainly as people are phoning to ask why I have not answered). Some, such as bank, medical and accountant, are important.
Though I download on to Thunderbird, I frequently go into Webmail to clean up stored junk and also block unwanted e-mail addresses so my first thought was that I had accidentally blocked some e-mails but I could not find them in the list.
I have therefore cleared all blocked senders and also added the e-mail addresses I am aware of to my trusted list in the hope that it might solve the problem.
My question is, "Do you think this is the likely cause and I should just wait and see if it solves it," or "Is there something else that could be causing it and if so what should I do to check?"
As it is only selected e-mail addresses I have to assume it is something I have done so I would appreciate if I could be advised any further checks I could make.
