Majordomo 1.9.4.1 & Reply-to capacity

Hi;

I was just reading the majordom FAQ when I came across this quote

"The most important reason why (setting )Reply-To: to the list is bad is 
that it can cause mail loops if any of the members of your list are 
running fairly-common but broken software which doesn't know what an 
envelope address is. (Many Microsoft products, as well as many other 
PC-based non-SMTP/Internet mail systems which work through an SMTP 
gateway.)"

Is this still true?

I have run a few list serves and been on many mailing lists where 
replies went to the list with no technical problems whatsoever.

Does this information apply to modern versions of majordomo?

Thanks for the info.

Steve
