291466 - No way to specify 3des like in outlook express

Status: RESOLVED INCOMPLETE

(MailNews Core :: Networking: SMTP, defect)

Description

[Brian 'netdragon' Bober]

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.

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

its pretty much no longer applicable, 15 years is long period for encryption and how it changed since then. I'm pretty sure 3des is no longer even negotiated anymore in current builds

So suspect the need for this protocol ended with the demise of registerfly.com
