Hi,

thanks for clarification. It all sounds reasonable. The only problem I
can see now is that if I create a new account on my machine and run
emacs there, then the value of user-mail-address is <login>@<hostname>
which doesn't refer to existing mailbox. I think that the header should
only be rewritten if these variables are known to have valid values. Do
you know how to do this?
