Update or remove

[Sam Lawrance]

These ports have fixable fetch problems. I'd like suggestions on what to
do with them. I'm thinking remove them for the reasons below, but maybe
that's a bad idea somehow:

gmime-1.0.7_1 /usr/ports/mail/gmime
Library (written in C) for parsing and creating messages using MIME

Could update to 1.0.8, but nothing in the tree uses it. gmime-2 seems to
be the active choice.

libspf-0.25.b /usr/ports/mail/libspf
Sender Policy Framework (SPF) library and client

Could update to libspf-1.0.0rc6, but again nothing uses it. libspf2
looks to be a more popular choice.
