Bug#292667: ITP: autoreply -- A safe, rate-limited autoresponder

[Chris Sacca <csacca@thecsl.org>]

Hi Bas,

> How is this different from vacation?
Autoreply is pretty similar to vacation, but hold some distinct 
advantages over it, at least for my deployment.  This package makes 
running a vacation-like service more secure, and requires less attention 
from the system administrator.

The main features that distinguish autoreply from vacation are:

   * As opposed to vacation that is per-user replys, autoreply can
     reply with many different messages via a procmail recipe
   * It remembers who it has replied to recently, and won't reply to
     them again within a specified interval
   * It has a list of addresses that it will not respond to
     (MAILER-DAEMON, majordomo, listserv, etc)
   * It examines headers, checking them for mailing lists, and does not
     reply if it determines the mail is from a mailing list
   * In case these features are insufficient autoreply also has a rate
     limiter so that it will not send more than a specified amount of
     replies in a given time. The rate and interval are both configurable.

Hopefully that is enough to convince you of the merits of autoreply over 
vacation.  If you have any other questions, I would be glad to answer them.

> BTW:  please fix your clock.
Although I find this terrible to admit, my clock was fine, I just had a 
broken installation of postfix so the message sat in my queue for a 
couple weeks before being sent.  This is also why I merged #292666 and 
#292667.

Thanks for your interest in this package.
