How do I submit a update to a port?

[Daniel Johansson]

Hi, I am a very new port-maker, got my first port in the portstree yesterday
:) /usr/ports/sysutils/pwsafe/

Anyway what I would like to know is how you do if you want to submit a update
for a already existing port. I want to submit a update to the bitlebee-port
but I didn't change much, only the version and make makesum so do I submit a
diff of Makefile and distinfo or should I mail the maintainer so that he
updates the port?
