I am trying to create my own extension for Thunderbird and one of the
tasks I have to realize is connected with outgoing mail. Every time new
message is sending I want to retrieve this message body and add some
additional information to the end of this message. There is a large
amount of interfaces that I can use for my task
(

but I don't know which of them I should use. I'm totally confused. It
seems that nsIMsgSendLaterListener and nsIMsgSendListener can be used
for my task, but I don't understand how exactly it should be done.
Could anybody help me?
Best regards, Alex Furman.
