It tries to set fd-limits unlimited , 1024 should be reasonable I think
if your server doesn't handle much connections. Master should be started
as root (bind to 143, pop + setrlimits).

This just tells (see man ulimit) that max open files is just 1024 which is
the default (filedescriptors for sockets etc). You need to be root to
setrlimit filedescriptors usually and thats why it says permission denied
there (running master as non-root?).

Example in ircd (sorry off-topic again): if you have ulimit -n 1024 then
you'll server will handle only ~1k connections same time (depends on how
many fd's opened) so usually before starting ircd we say
ulimit -n 10240 or something else.

I hope this helped (and shoot me again).
