$MATCH problem

I want extract from the body two consecutive matches..

i.e: subscribe mlist user(_at_)domain
               ^^^^^ ^^^^^^^^^^^
                (1°)     (2°)

I don't know how to handle it because if I put:

*^subscribe \/.*

i get MATCH="mlist user(_at_)domain" while I'd like something like MATCH1=mlist 
and MATCH2=user(_at_)domain(_dot_)

Is it possible?
Thanx.
