I have a Linux box I check/send email from via pop/smtp and all is well, though, it's secure. I got a new IP/host and had to make a couple changes.. hosts.allow.. ftp something (forgot the name).. and I think I have to add something to the qmail config to allow my IP to send out.. I was told by a friend that I need to "add the new ip as an acceptible relaydomain." However, I do not know where to do this nor does he, anybody ? 
Thanks
