SMTP option for DHCPv6

Dear all,

I was asked by the IETF DHC members to post this question here asking
for your opinion. I have recently submitted an IETF draft on SMTP option
for DHCPv6 protocol suite and presented my draft
http://www.ietf.org/internet-drafts/draft-cadar-dhc-dhcpv6-opt-smtp-00.t
xt during the last IETF meeting.
There is already a standardized SMTP option for DHCPv4. My question is:
Do you know any implementation where SMTP option is used by somebody for
delegating IPv4 SMTP server addresses to the clients? do you think that
the SMTP option for DHCPv6 will be used in the future by the email
clients?

Thank you in advance
