Try this to find the problem

% /usr/lib/sendmail -v myname@mydomain.com < /etc/motd

You should be able to tell from the output where it is not working or where it is stopping.

Things it could be:

1. It may be a firewall issue - firewall not allowing the traffic.
2. Could be DNS is not set up correctly - you must have the PTR record or servers will refuse the mail
3. Your server isn't connected to the internet (obvious I know but...)

Check sendmail with this command

% /usr/lib/sendmail -d0.1 -bt < /dev/null

You should get something back like:

% /usr/lib/sendmail -d0.1 -bt < /dev/null
Version 8.9.3

============ SYSTEM IDENTITY (after readcf) ============
(short domain name) $w = which1
(canonical domain name) $j = which1.mydomain.com
(subdomain name) $m = mydomain..com
(node name) $k = which1

WARNING: Group writable directory /var
WARNING: Group writable directory /var/spool
ADDRESS TEST MODE (ruleset 3 NOT automatically invoked)
Enter <ruleset> <address>

Fix the warnings by changing the directory permissions. The most important thing is that the domain name system identity is correct - it should have the same type of entries for your server. If not, it may not work correctly.

Double check that the place you are sending to exist.

Post back.

check-permissions(1M)					  System Administration Commands				     check-permissions(1M)

check-permissions - check permissions on mail rerouting files SYNOPSIS
/usr/sbin/check-permissions [login] DESCRIPTION
The check-permissions script is intended as a migration aid for sendmail(1M). It checks the /etc/mail/sendmail.cf file for all configured alias files, and checks the alias files for :include: files. It also checks for certain .forward files. For each file that check-permis- sions checks, it verifies that none of the parent directories are group- or world-writable. If any directories are overly permissive, it is reported. Otherwise it reports that no unsafe directories were found. As to which .forward files are checked, it depends on the arguments included on the command line. If no argument is given, the current user's home directory is checked for the presence of a .forward file. If any arguments are given, they are assumed to be valid logins, and the home directory of each one is checked. If the special argument ALL is given, the passwd entry in the /etc/nsswitch.conf file is checked, and all password entries that can be obtained through the switch file are checked. In large domains, this can be time-consuming. OPERANDS
The following operands are supported: login Where login is a valid user name, checks the home directory for login. ALL Checks the home directory of all users. FILES
/etc/mail/sendmail.cf Defines environment for sendmail /etc/mail/aliases Ascii mail aliases file ATTRIBUTES
