In effect, the person has one deal with, however it includes wild cards, e.g., “me.@my.domain'”, in order to suit any incoming deal with that begins offevolved with “me.” and ends with “@my.domain”. This may be very much like the “+” notation, however it could be even much less obvious, for the reason that deal with seems to be absolutely normal.
