Plesk 11.x / Windows :: Thunderbird 24.0 Outgoing Mail Settings

Incoming mail on several devices with various operating systems gives me no trouble at all. However I can not find the right settings for outgoing mail for Thunderbird 24.0.

For incoming mail I noticed I had to submit mail.<name>.be and port 143, no authentication and non-encrypted password. And it works.

For outgoing mail server I've tried a lot of options:

mail.<name>.be, all ports tested, all authentication options, and with both encrypted or non-encrypted passwords, in every combination of these settings.
smtp.<name>.be , all ports tested, all authentication options, and with both encrypted or non-encrypted passwords, in every combination of these settings.
<name>.be, all ports tested, all authentication options, and with both encrypted or non-encrypted passwords, in every combination of these settings.
