..therefore I cannot evaluate it.
Any plan for an updated version?

Questa recensione riguarda una versione precedente (0.4.1) del componente aggiuntivo. 

SMTP Control version 0.5.0 supporting TB 5.0 is in the review process.
Preliminary review is done. Possible download in version list section : https://addons.mozilla.org/en-US/thunderbird/addon/smtp-control/versions/
Comments from AMO reviewer is linked to the use of enablePrivilege() function, use of password field in prefs (but not used in the current version - for future use) and use of setAttribute() for oncommand and onclick commands. I'm working on it.
