No emails being received

[#1]

I use Thunderbird on a PC running Windows 7. After more than a year of successful use,  incoming emails have stopped yesterday and today, but I can still successfully send emails to a gmail account on another device. Another computer in the house is similarly affected.
Have no idea as to the cause.

I now think the problem is at my end. I will advise of progress later.

Ah no problem, I was just about to reply asking what errors you've been seeing, what mail clients you've been using and whether the email address is hosted with us.

Thanks, Adam. The problem was indeed at my end.
My email domain used by me and other family members had not been renewed on time. My oversight, but we are receiving emails again, thank goodness.
