Registerfly.com's SMTP server requires 3DES for SMTP but still uses port 25, and mail can be sent using outlook express. It's impossible to send mail using Thunderbird. Outlook Express has a security tab that allows you to specify 3DES. This is required to log in. I tried using SSL on both the default port and port 25, along with TLS. None of these worked. I'll attach a screenshot of the Security tab for outlook express.
Created attachment 181533 [details] Screen shot of outlook express's security tab The error I got was, " Sending of message failed: The message could not be sent because connecting to SMTP server <server name> failed. The server may be unavailable..."
Brian do you still experience the issue ? If so could you log what is happening at the smtp level and attach the logs to this bug ? Instruction on getting logs are avilable at : https://wiki.mozilla.org/MailNews:Logging
