About this Add-on
Due to restrictions of Thunderbird Add-ons website, the most recently uploaded version is downloadable on this front page. Currently it is the version 1.17.1 for Thunderbird 60 instead of the version 2.2.1 for Thunderbird 68, because 1.17.1 was released after 2.2.1. Please download 2.2.1 via the link "View other versions" if you use Thunderbird 68.
# Flex Confirm Mail
This is an extended version of the addon "Confirm Mail". You can define "exceptions" for confirmation.
## Exceptional Domains
You can define exceptions of "foreign" domains, via the configuration dialog or the preference `net.nyail.tanabec.confirm-mail.exceptional-domains`. If you put some domains to the list and you try to send a mail to an address listed in the exceptional domains list, then an extra confirmation dialog will be shown. The message of the confirmation dialog can be customized via two preferences: `net.nyail.tanabec.confirm-mail.exceptionalDomain.title` and `net.nyail.tanabec.confirm-mail.exceptionalDomain.message`. It will be useful in a case like: your SMTP server always encrypts your mail automatically but there are some exceptions.
## Exceptional Suffixes
You can define exceptions of attachments, via the configuration dialog or the preference `net.nyail.tanabec.confirm-mail.exceptional-suffixes`. If you put some "extension"s to the list and you try to send a mail with an attachment including a suffix listed in the preference, then an extra confirmation dialog will be shown. The message of the confirmation dialog can be customized via two preferences: `net.nyail.tanabec.confirm-mail.exceptionalSuffix.title` and `net.nyail.tanabec.confirm-mail.exceptionalSuffix.message`. It will be useful in a case like: your SMTP server always encrypts attachments but there are some exceptions.
* Add ability to emphasize recipient types (To/Cc/Bcc).
* Add ability to confirm when there are multiple foreign recipient domains in To/Cc.
* Show confirmation as "recipients are modified" when the composition window is opened for a draft.
