Thunderbird: Support for Server Name Indication?

Does Thunderbird support Server Name Indication (SNI)? I've been doing searches trying to find this out, but have not yet found anything. Thanks.


Background: My understanding is that a mail server (like exim) can use an SSL/TLS certificate specific to the domain of the sender's email address for encrypting submissions. But the email client (as in Thunderbird) has to support SNI as part of the STARTTLS process.

Looks to me like support has been in core since at least Firefox V2.

As Thunderbird shares the NSS component code with Firefox I guess Thunderbird supports SNI.

This bug includes a log containing SNI information for Google, so I guess it is not turned off behind some hidden preference. https://bugzilla.mozilla.org/show_bug.cgi?id=1411928
