I have postfix up and running, filtering emails though anomy and spamassassin. I need to add a vacation auto responder. I did search on here and see some stuff mentioned (ie Procmail, and vacation) However I cant really find any info on setting either of those up for a basic server setup like mine.
So any links, suggestions would be great.
Thanks so much.

vacation is part of the sendmail package. vacation is usually called from .forward, so it works with postfix's local delivery agent. You can read the man page here. Another possibility is maildrop, a delivery agent with filtering capabilities. It comes with mailbot, an autoresponder, although you can write your own: its filtering language is pretty serious. maildrop reads its instructions from .mailfilter, which resides in the home directory of either real or virtual accounts, so it's good for both local and virtual delivery.

I know you mention i can use vacation with sendmail with postfix but how. Is there a how to anywhere that anyone knows off. As far as mail drop I will take a look at that now. But I know diddle about writing anything.
Thanx bro.

You're welcome. Google turned up this guide for vacation. It looks decent. When you read it, keep in mind that the vacation interval is the the number of days during which a sender will receive only a single vacation response. So, if the interval is 14, anyone who sends you mail twice within any 14-day period will receive only a single vacation notification.

That link is outdated, but you along with the link set me about the right path.
Google for linux vacation got me to the Sourceforge page!
I downloaded and - unzip , untar and install with Had a couple of errors about the man pages, not important.
Its in it seems to work:
su to user i want to set up vacation for;
su username
and run vacation at command line
That takes u to a vi session where u can set your message.
Edit, save done with VI.
That also creates two files:
.forward (contains the command to do the deed)
.vacation.msg (what you just made)
vi them for further info.
Now
That sets the default .vacation.db file that says your away and sets it to run for 7 days.

Hope this helps.
DISCLAIMER - IM A NEWB if something is wrong here warn me ill fix it.
Rock on!
Blesings!

The only thing you're doing wrong is not understanding the interval specified with vacation -r. Contrary to what was mentioned in the guide to which I linked, the vacation interval is not the number of days that vacation will run, but rather the number of days each sender has to wait before he is eligible to receive a second vacation notice. I pointed this out in my previous post.

Examples:

1. Reply interval = 0. Send a vacation notice only to each sender's first email. Subsequent email by the same sender do not get a vacation notice:
2. Reply interval = 10. Send a vacation notice to each sender, so long as the sender has not received a previous vacation notice in the last 10 days.
