Postfix help. Need advise for email p-++++++

Okay I am trying to setup postfix to accept any emails with the "p-xxxxxx" and route them to one user. These email address will look similair to this
p-123456
p-987654
p-456789
etc
etc

I really could you some advise. Postfix is operating correctly and I can receive email for users that DO exist on my system. But when I try to setup a "default" user for all emails from p-xxxxxx the email gets bounced with an errot in the maillog indicating "p-343434 user does not exist" status=bounced.

Using sasl and sql I can use wildcards. I'm not sure if there are other options.

You want to use the recipient_delimiter function in Postfix. In your case you'd want to add this line to your /etc/postfix/main.cf

So by using the recipient delimeter what does that do? How does postfix know to send all mail beginning with p-xxxxxx to the same user?

Google broken today?

http://www.postfix.org/canonical.5.html

ADDRESS EXTENSION
When a mail address localpart contains the optional recipient delimiter (e.g., user+foo@domain), the lookup order becomes: user+foo@domain, user@domain, user+foo, user, and @domain.

Set the delimiter to - and then the lookup order becomes p-12233@domian, p@domin, p-12345, p with the first match being the addess that gets delievered to. You may want to use + instead of - as that's less likely to exist in a username.

No google is not broken. In fact I did google several times for this information before I posted here. The problem is the terminology used in the descriptions. Not all of us are as gifted at understanding the tech speak that man pages usually are written in, so i apologize if my questions comes off more "noobish" than normal. What I have done so far
changed recipient_delimiter to "-"
reloaded postfix in order for change to take effect
create an alias in /etc/aliases for
p: username
ran newaliases to rebuild aliasdb.

However email sent to p-xxxxx is still being bounced do to postfix not recognizeing the username. I am beginning to think that may alias may be at fault, so I googled for that, but I can't seem to find any similiar situation out there that may apply to my situation. Then again I may not be searching for the right things.

Hmmm testing on two servers and it works in both places whether I use - or +. Even on my funky virtual domain box that I need to fix soon.

Do a postconf -n and post the results.
