Thank you to all of those who sent me comments on the first draft. A new version of this is now available that I feel addresses the concerns that were raised privately and on the list. Please let me know if you have any further suggestions. thanks > ---------- > From: Internet-Drafts@ietf.org[SMTP:Internet-Drafts@ietf.org] > Reply To: Internet-Drafts@ietf.org > Sent: Tuesday, February 11, 1997 6:36 AM > Subject: I-D ACTION:draft-gahrns-imap-referrals-01.txt > > > A Revised Internet-Draft is available from the on-line > Internet-Drafts > directories. > > > > Title : IMAP4 Referrals > > Author(s) : M.
