sending email through PHP not sending!

[advil0]

I'm trying to get php sendmail on Ubuntu 10.04 LTS to work correctly and it isn't working at all.

Heres my "sendmail.mc" file.

# cf/debian/sendmail.mc.  Generated from sendmail.mc.in by configure.
#
# sendmail.mc prototype config file for building Sendmail 8.14.3
#
# Note: the .in file supports 8.7.6 - 9.0.0, but the generated
#	file is customized to the version noted above.
#
# This file is used to configure Sendmail for use with Debian systems.
#
# If you modify this file, you will have to regenerate /etc/mail/sendmail.cf
# by running this file through the m4 preprocessor via one of the following:
#	* make   (or make -C /etc/mail)
#	* sendmailconfig 
#	* m4 /etc/mail/sendmail.mc > /etc/mail/sendmail.cf
# The first two options are preferred as they will also update other files
# that depend upon the contents of this file.
#
# The best documentation for this .mc file is:
# /usr/share/doc/sendmail-doc/cf.README.gz

If you need anything else, ask for it and I'll post it here.

Any ideas?

May be try troubleshooting your TCP connectivity as shown here Quick HOWTO : Ch21 : Configuring Linux Mail Servers - Linux Home Networking It will help you to figure where exactly it fails...also check for errors at maillog file.
