Is anyone out there using their primary roadrunner machine (i.e. the one with the "live" IP address) as a mail relay host? Most domains accept my mail just fine but others (xo.com, aol.com most noteably) reject my mail returning some version of the following error:
... while talking to triton.xo.com.: >>> MAIL From:<[EMAIL PROTECTED]> SIZE=866 <<< 501 5.1.8 <[EMAIL PROTECTED]>... Sender domain must exist I imagine this is due to roadrunner not adding my host name, paloverde, to DNS when it assigns the IP address. So, the question becomes is there any way to fix this so I can mail my partents at their AOL address using my machine (paloverde) as a mail router? And, just in case anyone is worried, I am an avid anti-spammer and I'm not trying to use my machine to spam. I am running RH 7.1 and I checked the /etc/mail/sendmail.mc file but I can't see anywhere in the file where I can fix this problem. Any help would be greatly appreciated. Thanks! Greg
