As I understand it, addresses with trailing dots and other odd
characters in the local part are not RFC valid - are they
realistically used across the network?
On that assumption, should the general local part validation of
addresses accept those forms, be modified to reject them (which
obviously *can* be done in ACLs), or modified to reject them with an
override (like the helo characters one)?
Modifications would be an incompatible change - working configurations
could then be stopped working, which might be a good thing (unless you
are the one caught out by it).
