Bouncing Email
Hello. Im running redhat 7.2 up2date as of yesterday. have a linksysrouter that forwards ports 22 25 110 80 21 to my linux box and everything works great except When i send mail to my domain from another domain ex yahoo, it gets bounced back? i can send mail from my box to the other domains. and i can even send from the box to another user on the box and the other user gets the mail. its just when i do it externally it dosnt work. I nmapped my domain from a friends box and it says port 25 closed but when i nmap it from my box it dosnt show 25 and when I nmap localhost from my box it says port 25 open. im not sure what the prob is, any help would be great. please let me know if i need to clear up the question ill be on all day today, ill be quick to respond. thanks.
