Yesterday I noticed that no new emails had arrived in hours, including several that should have arrived. In Firfefox, I sent a new email - it showed up in the "sent" folder but not in the inbox. I cleared Trash and Spam folders even though there were only 9 emails there. I sent another email - no joy.
Then I looked at the Sent folder - zillions of emails were there. How can this be? Lots of them were years old - how can this be? So, I cleared the Sent folder and then new emails worked again.
Normally, I use Thunderbird with POP3 settings. Isn't that supposed to remove emails? Or do I have to manually clear the Sent folder every so often?
Also, any emails sent to me during the failed time period haven't shown up. Is there any way to get them? I am very confused - it's like Comcast thought my mailbox was full. Was it?
