Thanks.

That is good idea. It is nice hack. Intercept the file, change it a
bit if necessary and delegate to editor.

I think in this version I will not get the To: field, I will get the
reply message.

What I need is recipient's email to associate it with the ID from the
database. I could maybe pipe it, get the Email, associate with ID,
store it somewhere, then launch editor that is anyway Emacs that could
by the file name recognize that it has to insert ID if not inserted. 

Maybe first piping, getting email address, recording ID, then reply as
usual. The ID actually need not be in the text, it can be outside of
Mutt, important is that I can access the "current ID" from editor. 

This is all good as brainstorming.

Also good idea. That is what I have to do.

Thanks.
