Very helpful when creating new messages from sent ones with many recipients.
Does anybody have experience, whether this add-on is compatible with TB5?

Thank you, thank you. Just what I wanted. Makes it easy to remove an address from a list when sending.

notto 0.5 and Thunderbird 3.1.2 worked for me. Made a list of five addresses. Put that list in the "To:" field. Put one through four of the addresses in its own "NotTo:" field. Filtered correctly in four of four tests. Put the list in the "To:" field. Placed the five addresses in their own :NotTo:" fields. Got "No Recipients Specified" Send Fail message. One of one successful tests. Put the list in the "To:" field. Placed the list in the "NotTo:" field, also. Everybody got the message. So -- six of six tests were successful. Not extensive, no, but STILL batting a thousand. I used notto 0.4 constantly, and have been waiting (almost) patiently for an update. Thank you, andreifa! I laud your efforts!
