I have a WinXP machine masq through SUSE Linux 7.1 (2.2.18) machine. But I cannot send email. Here's the message Outlook gives me:
"The message could not be sent because one of the recipients was rejected by the server. Server Response: '5220.127.116.11 <email@example.com>...Relaying denied. IP name lookup failed [192.168.0.2]'. (Account: 'firstname.lastname@example.org',SMTP Server: 'myserver.domain.com', Error Number:0x800cc79)."
Is there something I need to fix with the SMTP server on the linux box? Or is there something in Outlook I need to fix to get the problem resolved? ??? Thanks.
Well I will take shot at this, since I know practically nothing about sendmail. I keep looking at buying O'reilly's 1000+ page book on Sendmail and setup my own mail server, so I can learn about it. But just have not had the time.
Do you have the ip address and hostname of the windoze machine in /etc/hosts on the Linux box?IP name lookup failed [192.168.0.2]
It looks like sendmail was trying to do a reverse name lookup on the windoze box and it failed.
