Question about courier-imap and maildrop

[viq]

I am looking at setting up a mail solution for my home usage, and
those seem to be a popular option from what people on the net seem to
say. But, when looking at what we have in ports I noticed the versions
are over 2 years old... So here's my question - did anyone have, or is
aware of, any problems with them that would be fixed in the newer
versions? Is anyone actually running those, or self-compiled newer
versions thereof? Any issues with them?
