Subject: [Imap-protocol] which IMAP servers support support SASL
 authorization vs. authentication ID?
Message-ID: <alpine.OSX.2.00.1201130725430.38441@hsinghsing.panda.com>

I have been tasked to identify which IMAP servers support the SASL concept
of authorization vs. authentication ID and if it is suitable to allow
impersonation; that is to proxy to various user accounts.

I have the following data:

Panda IMAP:		Yes
 	;; Authenticated userids in system group "mailadm" may authorize
 	;; to any other userid.

UW IMAP:		Yes, in newer versions
 	;; Same as Panda


Probably yes, but not sure and need details:
