i assume you mean shell wildcards,
which are not regular expressions in
the regexp(6) sense of the word.

despite your comment i don't understand why you
are messing with eval here.  using eval is almost
always wrong.

; dropuser=(reply.yahoo.com!calendar-invite)
; addr=reply.yahoo.com!calendar-invite
; if(~ $addr $dropuser) echo drop
drop
;
