Need vacationautoresponder software

Greetings.

I'm looking for a vacation-style autoresponder program which has the following features:

0. Runs on a GNU-Linux with local mail spool files. This means I need to be able to invoke it via .forward, procmail, or similar.

1. Doesn't reply to spam, bulk messages, mailing lists, mailer daemon bounces, or any mail sent from a blacklisted address.

This means the program should have some sensible defaults for filtering mail based on headers such as Precedence, List-Id, etc. I should also be allowed to enter a list of regexps to be matched against arbitrary message

2. Won't send an autoreply to the same address more than once every n days.

3. Allows senders to unsubscribe from the autoreply service. (That is,

4. Most importantly, I need to be able to send different autoreplies based on the address the original message was sent to.

For example, say that I'm the manager of a company, and I'm also president of some social club in my spare time. I also have a personal life. So work at home, the latter two accounts are forwarded via their respective mail servers to my personal account. On my local machine, fetchmail then connects to the remote mail server via POP3 and downloads all messages and delivers them tovar-spool-mail-foo. Procmail is also involved to filter the messages through Spambuttbuttin.

I need the vacation program to examine each incoming message and send the message "Sorry, but I'm not in the office; please contact my secretary" to only on weekends; please be patient" to all legitimate mail sent to e-mail only once per month, so you'll have to wait" to all legitimate mail

I found a lot of vacation programs on freshmeat but as far as I can tell none of them support Feature #4 above. I don't think any supported #3 either, but I know such software must exist because I've received autoreplies from people which had unsubscribe instructions.

Any suggestions would be appreciated.

Regards, Tristan
