This feature works for me but I use FEATURE(virtusertable) instead of mailertable
to pass mail to my custom mailer:

#virtusertable
# the following rule diverts mail to "plussed" (and only plussed) destination addresses to custom mailer
++ at realdomain.net  %1%3 at realdomain.net.pseudodomain
#EOF

(mailer definition has CPpseudodomain for this to work).

Maybe it works for mailertable too, try it.
