Outgoing email character encoding
Hello team, In our Greek company (ATTIKO METRO SA) we are using mozilla thunderbird as the default email client in windows PC Systems for many years .
We have applied the option of sending email with character encoding Greek (ISO-8859-7) and also the same encoding as default encoding for Incoming emails (if not defined at message header). (see attached image) In config editor these options are mailnews.send_default_charset and "mailnews.view_default_charset".
After update to version 91.x this option disappeared and now the character encoding for outgoing and incoming is UTF-8 and cannot change it. It is very critical for us to have this option again because all our emails have to be encoded in ISO-8859-7 according to our installations and policies.

Is it your company's policy that emails be encoded in ISO-8859-7? See https://bugzilla.mozilla.org/show_bug.cgi?id=862292
Yes. It is the policy. I know about UTF-8 but we have to use ISO-8859-7. Thank you
If you go through the task that was filed in Bugzilla as linked to in my previous reply, you will see that those preferences were removed and going forward, Unicode will be the encoding of choice for outgoing and incoming mail. This change was made years ago and I doubt there are plans to restore or even maintain code for non-unicode encodinng. If changing company policy is not an option, I'm afraid you have no option but to revert to the version of Thunderbird that still offered non-unicode encoding options. That, of course, introduces the problem of security holes in unpatched unsupported old software.
