Lists are not working in current version of Thunderbird
My version of Thunderbird just updated this morning and as I went to send an email to a "List" I get an error saying "BPS <"Entire School list"> is not a valid e-mail address because it is not of the form user@host. You must correct it before sending the e-mail.
I've used this list for years and today it has stopped working. Please fix this little bug.
