Using wildcards in sendmail for aliases

JetreL · 11-29-2006, 08:57 PM

I am hoping someone here can help me with this. I am using sendmail and need to figure out a way to use wildcards for aliases. What I am looking to do is all mail that meets a certain wildcard goes to an address and all the rest of the mail goes to another address. I know how to do the last part using:

@domain user

But the first problem has me stumped. An example of what I am looking for is:

%smith%@domain johnsmith
@domain user

Ideas?

There's some info at http://www.sendmail.org/m4/features.html which looks like it might do what you need. Unfortunately, I haven't tried this...

Code:

Additionally, if the local part consists of "user+detail" then "detail" is passed as %2 and "+detail" is passed as %3  when a match against user+* is attempted, so entries like

old+*@foo.org	new+%2@example.com
gen+*@foo.org	%2@example.com
+*@foo.org	%1%3@example.com
X++@foo.org	Z%3@example.com
@bar.org	%1%3

and other forms are possible.

Note: to preserve "+detail" for a default case (@domain) %1%3 must be used as RHS. There are two wildcards after "+": "+" matches only a non-empty detail, "*" matches also empty details, e.g., user+@foo.org matches +*@foo.org but not ++@foo.org. This can be used to ensure that the parameters %2 and %3 are not empty.
