[Lowfer] My message reply problem

[Andy - KU4XR]

Here's what I've noticed, When post goes to the list, and I try 
to reply, many of them are showing who the post came from in the
" TO " line " , and a lot of those when I reply don't get there.
I've noticed that when I reply, if the " TO " line shows;

"Discussion of the Lowfer (US, European, &  UK) and MedFer bands" <lowfer at mailman.qth.net>

Then the reply makes it to the list, just as this one did.
