Once I send an e-mail from 'sendmail-query-once', 'send-mail-function'
is set to 'sendmail-send-it' in my config file by the
'sendmail-query-once' process. Things then work until I restart emacs.
After restarting emacs, message-mode tries to incorrectly guess the
'From' field of my e-mail even though it is already present.

I'm sorry, I misspoke, I meant that I'm not defining
'send-mail-function' in my config file. I just checked and it is indeed
set to 'sendmail-query-once' when not set in my config file.

So this is my problem, when 'send-mail-function' is set to
'sendmail-send-it' or when 'message-send-mail-function' is set to
'message-send-mail-with-sendmail', somewhere in the message mode, the
code tries to guess my From and sets it incorrectly event though there
is already a valid from in the message.

To get things to work, I have to remove those settings set by
'sendmail-query-once' from my config file and restart emacs. Things then
work for that session.

Sorry for my bad initial explanation.


Thanks,
Emmanuel
