I am fairly new to sendmail, and having a tough time with configuring a new install. I am stuck on site till I get it figured out. This is what I have. I just installed everything on my redHat 7.3 CD's. I can telnet from the server to it's IP -p 25, and 110 Users can retrieve, but not send mail, and others can send mail to the server from the outside. I am using Webmin to manage it. This is the error I get when trying to send from an Outlook Express client: Relaying Temporarily denied. Cannot resolve PTR record for x.x.x.x port 25 In /etc/mail/access If I add the (private) IP address of the workstation which is trying to send the mail it all works perfectly. I have tried to enter the network number instead, but can't seem to find the right syntax for allowing a class C. Maybe my problem is something else entirely, but I sure could use some help, so I can hit the road. Thanks in advance -- Raymond Norton Little Crow Telemedia Network 320-234-0270
