This is an absolute MUST have addon! Specially for us poor souls who are stuck with a shared server :-)
Imagine you have a domain name www.abc.com and you an email id [email protected] Every time you try to send a mail through [email protected] (using Thunderbird) you are prompted a security confirmation, with the dialogue box having the following heading:
Security Error :: Domain Name Mismatch
This happens because your domain www.abc.com is in a shared server that has hundreds of other domains too. And therefore the certificate that your server presents to Thunderbird does not have your domain name (www.abc.com) anywhere in it. And so Thunderbird thinks that it to be a scam!
This addon makes you confirm once and then Thunderbird never again asks for the confirmation. Brilliant! One feature that should be inherent in the Thunderbird application itself. Thanks a lot to the developer :-)
