Redhat sendmail help
Hello all,
I have been trying to understand sendmail. I'm having problem sending mail to another machine on the same network. I keep on getting error "Deferred: Name Server :redone: host name lookup fail". I can ping the machine and log in via ssh no problem. I don't have a DNS server. Is this because sendmail is looking for host via the DNS server instead of /etc/hosts. I have edit my /etc/resolv.conf file to not look for a nameserver just the domain. But the same thing. I can mail to a user on the machine locally. I can telnet to the smtp port locally but not from the out side ( another machine). I have edit my /etc/hosts.allow to include the other machine. I have also look at the posting here and edit the sendmail.cf to accept unreolv hostname and account and recompile. This doen't work. I'm lost. I'm currently running redhat AS3. Any help would be great. THANKS

sendmailconfig
SENDMAILCONFIG(8) System Manager's Manual SENDMAILCONFIG(8) NAME
sendmailconfig - configure sendmail for Debian systems SYNOPSIS
sendmailconfig [--no-reload] DESCRIPTION
sendmailconfig is used to simplify the configuration of sendmail(8) for use on Debian systems. In the simplest case, you may run this program to (re)configure sendmail for your Debian system at any time. It will modify the file /etc/mail/sendmail.mc in order to create a working sendmail configuration which will be written to the file /etc/mail/sendmail.cf. For advanced configurations, you can modify the sendmail.mc file before generating sendmail.cf. Future invokations of sendmailconfig will preserve these changes provided they are made at the end of the file. Normally sendmailconfig will ask if you want to reload sendmail after making changes to its configuration. The --no-reload option will avoid this question. FILES
/etc/mail/sendmail.mc sendmail m4 input to generate sendmail.cf /etc/mail/sendmail.cf actual sendmail configuration file /etc/mail/sendmail.cw names for which we will accept mail in the standard configuration /etc/mail/sendmail.ct names of trusted users in the standard configuration SEE ALSO
