can't send e-mails
When I open my Thunderbird e-mail on my PC, I immediately receive a pop-up saying "failed to connect to server hp110.hostpapa.com." Hosp Papa is a web site manager that I use, not a server, at least that is what I was told when I called them about the issue. I ignored it for a while and everything worked, but now I can't send e-mails. I can receive no problem. I have a business to operate, and it is getting very difficult when I cannot receive e-mails. Can you please tell me what to do? How do I find out what version of Thunderbird I have? Thanks! Bev
