using virtual_aliases I maintain separate domains each with their own
aliases for users in that domain
maintain a file /etc/exim/domains/virtual_aliases merely a list of the
virutual domains

one
two
three

then each domain has an alias file
/etc/exim/domains/<domain.name>/aliases

jzaw:     jzawone
bill:        billone
freda:    fredaone


jzaw:    jzawtwo
terry:        terrytwo


bill:        billthree
freda:    fredathree


so mail is delivered
jzaw@one => jzawone/Maildir
jzaw@two => jzawtwo/Maildir

mail delivered to ~/Maildir for each user

jzawthree in domain three does not exist so mail to jzaw@three gets
bounce/rejected/dropped whatever
but doesn't get delivered to any other Maildir and not to a local user
either cos there is no local user jzaw
