Fedora :: Use Mail Without SSL As May Occasionally Use Unencrypted WiFi?

I upgraded to FC15 in early june, come June 15 Thunderbird suddenly ceases to send or receive any email. It pops up with the message "You may have exceeded you maximum connections" and I've tried changing the cache connection count to 1 instead of the default 5 and every OTHER post about that error suggests to no avail. Funny thing, my primary desktop is still on FC13, same thunderbird version, arch and account setup (with SSL enabled) and works flawlessly. Even with -safe-mode enabled it doesn't work. My lightning calendar also doesn't sync since then.

I have found that if I turn SSL off IMAP works again, SSL SMTP still fails. If I turn SMTP SSL off it sends mail. The calendar is an https (SSL) link. Obviously the issue is SSL and Thunderbird in FC15. There are no errors/messages in the console, maillog or the in-built error console. I will NOT use mail without SSL as I may occasionally use unencrypted WiFi.
