Because in the configuration place of many MUAs, the Reply-To address is 
located in the very near of the mail address, some people may think they 
_must_ fill a value there, because they won't get a reply otherwise.

I had some troubles with a very few mailing list managers as well, so I 
tend to always add a Reply-to when mailing to lists.
