Update or delete port, how to decide?

I recently got an email from the package building machine (14-current) about a port (mail/xmail) that I created quite a number of years ago that no longer wants to build.
Is there a way to tell if anyone is still using it so I can figure out if I want to invest the time in a major update to the port, or whether it should just be removed.
Thanks,Steve Roznowski
