[Samba] Resend of returned email: [3.6.6] Possible to allow password-free read/write access?

[Linda W]

Why would the samba list be looking for a reverse host name
via IPV6?   IFAIK I only have an IPv4 addr and reverse
addr.  I don't know if the original went to the person
in france or not.

Anyone else getting  bounces like this?
