Hi!?
Now I'm programming Webmail Solution by using Debian + IMAP +MySQL +Exim.?
?
I set up configure file for exim to use autoreply function.?
But It's not working. Can you tell me which part am I wrong??
?
vacation_transport:?
  driver = autoreply?
  file = /home/softwise/${local_part}/.vacation.msg?
  file_expand?
  log  = /var/log/vacation.log?
  from = nicedirkt@????
  return_message = true?
  to = $sender_address?
  subject = "Re: $h_subject"?
  ?
This is what I wrote at Director.?
?
Vacation:?
  driver = localuser?
  require_files = /home/softwise/${local_part}/.vacation.msg                 ?
  no_verify                                                   ?
  transport = vacation_transport                                            ?
  unseen ?
?
And what about .forward file. Isn't it necessary at vacation_transport or Is exim recognize .forward file automatically??
I'll looking forward your reply.?
Thank you~!?
