Thamkyou. A year ago after decades of thunderbird, I was required to sign into email everytime I went to or back to email. I tried to find answers online and w/ISP. ISP said it was email problem. 2. Every year or 2, my email stops. When I call, the say it is thunderbird until I ask to verify ports. They come up with different ports. They say I need to use map instead of pop. I used pop as they first stated to use and then they wanted me to use imap. After trying ports they choose, it was ok for a while. I started out w/ assurance, name change to domain.com, then web.com and now NS. They could not find my email in th past and then stated it was on a different server. Which I think means there was a missing link. I am a user, not a programmer. I created 450 web pages with DW and was amazed they all passed online, still do. Now, with NS, email is stopped. They want me to use web mail and I do no. They stated to use outlook. I prefer thunderbird because I was told decades ago that thunderbird and Netscape were the best because they keep it simple W/O excessive links cluttering up the home. So, now my email shows that there is email commit I need the trailer on bottom of page but it does not show up. So, I did get a message earlier Wed that thunderbird rejected "imap". ISP said not their problem. I am 83, disabled vet and have tried evey combination of ports, pop, imap for days and hours with no avail. So you are right. I am an idiot. My bank, cell phone co,, utilities and others recognize me by my email. I have many directories of frequent contacts from people I have deal with. I also save trash because it is a source of records. When it works, it is great.
