RE: [opes] draft-ietf-opes-smtp-security-01

Hilarie,

your advice is well taken and your help is much appreciated :-)

I am very ok with adding this sentence to the Introduction as you propose
and if you want to provide some paragraphs to the document, that'd be
excellent.

Tony/Markus: As this has been raised during the WGLC, I am awaiting your
call whether we should create a new revision of the document.

Hilarie: Would you be able to send those paragraphs within less than a week?
I am going on vacation for the holidays and would love to get this finally
done in 2006 ;-)

Regards
Martin
