How do I let people know that I'll be on vacation?

Use the Unix vacation program. The vacation program will only send an auto-reply to each person who sends you mail only once, so it's best to include your return date. Also, vacation will not send auto-replies to mailing lists (it only replies to messages that have your address in the To: field)
Open up a terminal window and type:

vacation

Answer a series of questions. When you are done, your vacation message is set up.
You can specify dates and allow the vacation program to automatically return to normal mail when you return. Or you can do it manually by running the vacation command again when you return.


This program can be used to answer your mail automatically when you go away on vacation.
