How do I shut off postfix? I don't see anyway that actually keeps it shutdown. I don't seem to be able to start sendmail with another MTA running. I check back and there is postfix still running after I shut it down.

Wait I'm confused... where are you seeing Postfix running? The log you posted only shows lines about sendmail and PostgreSQL... nothing about Postfix.
And the error you're getting with Sendmail isn't because Postfix is still running. If that were the case you'd get errors about Sendmail not being able to bind to port 25.
You might want to search Google on the "fatal: flush queue mode requires no recipient" error and see what the solution is.
Hi,
I assume postfix is running because everytime I return to the postfix module the button says stop postfix.
I even took postfix out of bootup yet it shows up as running
Doing a google search I found this interesting note:
""> The output said:
> Starting sendmail: [[ OK ]]
> Starting sm-client: sendmail: fatal: flush queue mode requires no
> recipient

Yes, the usual RedHat insanity. Suppress real output, replace by
meaningless self-generated output.""
But I got no answer on this fatal flush queue thing, except to revert to postfix.
This turned out to be a RH feature thingy. I needed to actually go root and and use a routine to turn one or the other off.
can you elaborate on this RH Thingy as i am having the same problem and cannot find a good answer to this
I think he is talking about "alternatives". Try the following commands for more information:
alternatives (should be in /usr/sbin by default)
man alternatives
alternatives --display mta
ls -l /etc/alternatives
Alan is quite right. Using the alternatives command for the switch is strongly recommended (you can do it manually, but you'll end up breaking stuff if you don't get the steps and links exactly right).
I'll also add that "alternatives" isn't just a "Red Hat thingy". It is also the recommended way to make this kind of change on Debian and Ubuntu, as well (in fact, it was created for Debian and Red Hat/Fedora adopted it as the "Right Way" to handle this particular set of problems). I suspect many other distros also use alternatives.
