Mail for vacation

[jean-marc delpech]

Hi all, my configuration : cyrus-imap 2.0.9 / sendmail / redhat 7.0 is working well. When your are in vacation and someone send you a mail, have someone got an idea to reply to this mail "sorry, I am in vacation and I will be there in 3 days" I would like something very simple for use by each user. Thks for yr ideas
