Check the above for the weird error message I get. Tech support says sendmail is working just fine. I double and triple checked the path. not sure what -i is for.

We ran into so many problems with the sendmail MTA that we replaced it with postfix on our sites.

you'll probably get your issues resolved and be up and running sooner and with less frustration

I'm up and running now. I'm running through SMTP. Trying to configure sendmail because my SMTP host has  a limit of 500 emails per day.

On Administer CiviCRM >> Global Settings >> Outbound Mail, if you configure SMTP then the host that's running CiviCRM will make a connection to the hostname and port you specify on that page and use that host to send mail.  If instead you configure sendmail with a path of, for example, /usr/sbin/sendmail and argument -i, then CiviCRM will run the /usr/sbin/sendmail program on the host where CiviCRM is running and pass it the argument -i, with the mail to send.  So in your case if you were using some different computer to send mail than the computer where you run CiviCRM, that might make a difference in your limits.

Our sites don't handle incoming mail, that's done by Google Mail.  So we prefer to block port 25 to keep the bad guys out, which means that we send mail by running the sendmail program rather than connect to the computer's port 25.  Needless to say, we can only do this because there is a sendmail program on the same computer that runs CiviCRM.

The documentation for sendmail is at http://www.sendmail.org which seems to be down at the moment so I can't give you the exact link to the -i argument.
