Sending a message to a mailing list adds the mailing list name in  
front of the real mail address list in the To field. The To field then  
looks like this:

To: [LIST_NAME]: [MAIL_IN_LIST1], [MAIL_IN_LIST2],...

This format is not compatible with the following RFC:  
https://www.rfc-editor.org/rfc/pdfrfc/rfc5322.txt.pdf

Sending such a mail is not a big problem in most cases but some mail  
clients have problems once "Reply to all" is used on this mail since  
the list name gets interpreted as part the first mail address in the  
list.
