Hello, I work outside my company. I have a problem sending messages with the IMAP protocol with the server of my company (the same for incomung and outgoing) with this settings: Server type: SMTP, Server Name:, Port: 465, Security: SSL/TLS, Authentication: normal password. The server "" responds "connection timeout". For incoming messages it works very well with this settings: Server type: IMAP, Server Name:, Port: 993, Security: SSL/TLS, Authentication: normal password). More details in the screenshot attached. The same problem using Windows Live Mail with error code 0x800CCC0F. The problem does not exists using Microsoft Outlook. Can you help me to understand the problem and where is localized ? Thanks very much.

Reproducible: Always

so your configuration isn't right. Issue isn't specific to thunderbird as you have the issue with Windows live. What does your IT support says ?

I'm having a similar problem with outgoing email on Fedora 14 and Thunderbird 3.1.7.  My email sending works with Thunderbird on Centos 5. and on Thunderbird 2 under Ubuntu 9.04.

When I try to send, the server connection times out.  We are a very small company and my "IT support" is my partner who handles the email server.  However, if the configuration is correct on two other systems, I don't understand why it should be incorrect on my Fedora 14 system under a newer version of Thunderbird, except that something changed in Thunderbird.
Reporter, do you still see this problem when using version 10 or newer?

if you are unable to reproduce, please close by setting status to resolved, and resolution to WORKSFORME or another appropriate setting.

If you are able to reproduce, please add new details, and a testcase if one does not already exist in the bug report.

Sorry, but I missed the question.  Yes, this happens for me with version 10 on Centos 5.  The only way we can make use of outgoing email on Thunderbird is apparently to select an insecure, password-in-the-clear approach even though the server offers SSL/TLS.
