Alright, this has been going on for about... 2 weeks now? I finally got fed up with it today, did a lot of searching, found people with the same issue, but no ways to fix it. Basically, I have two gmail accounts. I can receive email just fine, but I cannot send it. When I do, it comes up saying can't use the server smtp.gmail.com:email@example.com. It offers to let me use another smtp server, but being gmail, it doesn't work either. Mail Diagnostics show connection to the internet, but has issues with the smtp server at times. It is sometimes listed as Offline, sometimes not. I have "Use default ports" selected, those being 25, 465, 587 under under the "edit smtp server list" on account information. Nothing under "IMAP Path Prefix" Port: 993 with use SSL checked. Authentication is password, and works. That's all the info I can think of to provide you with, if you need anything else, just ask. Thanks.
