Documentation
Alternative header demarcation for queued messages.
If you sometimes get alternative values for mail-header-separator in
queued messages, set the value of this variable to whatever it is.
For example, rmail-resend uses a mail-header-separator value of empty
string ("") when you send/queue a message.
When trying to send a queued message, if the value of this variable is
non-nil, feedmail will first try to send the message using the value
of mail-header-separator. If it can't find that, it will temporarily
set mail-header-separator to the value of
feedmail-queue-alternative-mail-header-separator and try again.
