For the purpose of enabling RPOP in nmh, included below is an edited
selection of my quickie patches.
After applying the patches, use --enable-nmh-pop and --enable-nmh-rpop
with the configure script.
Disclaimer department:
- These patches were made against nmh-0.27, so they might need to be
tweaked to work with nmh-1.x.
- Some other stuff is mixed in as well, such as code to support a
-nopop switch, so use these patches with caution.
- Note that RPOP is pretty insecure, which is probably why it's not
enabled by default in nmh--or qpopper, for that matter. For one
thing, the "inc" and "msgchk" programs need to be setuid to root for
RPOP to work, so that adds another dimension of possible insecurities.
Not recommended for most sites.
- I promise nothing; your mileage may vary. Keep a copy of your
original source tree so that you can revert if something goes wrong.
