email address matching algorithm?

Hi guys,

Does anybody know any very efficient algorithm that can check a email address with a set of addresses or domains with wildcards?

Example:
pattern 1: *@a.b.c
pattern 2: joe@*.b
pattern 3: mary@*.b.c
pattern 4: *@*.c
pattern 5: mark@a.b.c
pattern 6: *@*

input address: mary@a.b.c

After computation, the pattern 1, 3, 4, 6 will be selected.

i do not have one myself but know that regular expressions'd do this just fine and have been used to do this many times

have a search for "regular expression email validation" and i'd be surprised if you don't get something useful from that.
