port maintainer wants to change port maintainer email address

[joeb1]

Hello,

I maintain 4 different ports. The port maintainer email address listed with
the ports have been harvested by spammers and I am now receiving over 100
spam emails per email address each day.

The ports in question do not require update. Just want to change the
maintainer email address.
Is there some way this can be done without bumping the port version number?
