This is incorrect. The servers of my provider didn't support secure authencation with an username and password, so I can't send e-mail until I turn it off. I had the problem at 6 different (from family, etc.) PC's, with Windows XP, Vista and 7. Reproducible: Always Steps to Reproduce: Upgrade a Thunderbird 2.x-installation to a Thunderbird 3.x-installation. Actual Results: All SMTP-servers are set to use secure authencation with username and password. Expected Results: It has to adopt the settings that were made in Thunderbird 2.x.

David, I thought that your second patch for bug 522633 had disabled the auto-probing for secure authentication for Thunderbird 3.0.2, still there? Either way, it's a duplicate.

Yes, autoprobing for secure auth should be turned off in 3.0.2 - if trySecAuth is not set, we should not be setting useSecAuth.

To Joost: Do you remember which box was checked in the SMTP Server dialog? Was it "Use secure authentication" or "Use name and password", which are different settings? Only the first case has been fixed thus far.

To rsx11m: It was "Use name and password". Excuse me, I didn't describe it clearly!

No problem, thanks for confirming. That's actually a bug in the old TB 2.0 account wizard (see bug 556984 comment #13 for related discussion) which only surfaced after migration to 3.0, now handling authentication more strictly.

Sorry, make that bug 524868 comment #13...
