I'm using Slackware 1.2.8 and it seems like I can
send mail to other people on the internet but
it doesn't work the other way around. People
try sending back mail to me but my pop
server never seems to receive them; also those
people who sent me don't get an error message
from their mail daemon until 1 or 2 days later.
Another weird thing is that I can send and receive
mail within my hostname (that is, for example,
another user on my system can send to and receive
from root). Thus, the pop server seems to work
within my hostname but not outside. Can anyone
help me? Thanks...
