Yeah. TCP guarantees the data is good. You basically can't get corruption
unless one side or the other is broken.

MTA configuration is huge. And it's a big black art. And not all of what
makes for good delivery is obvious. You have to sit down and get into the
system to your elbows, as you grow. (Oh, and at times, you'll find you have
to redo stuff, because there are places where the paradigms change -- you
scale to some point, and then you have to rethink how you do things...)
