Hi Doug, thanks for the run down, Can I ask how you did this.
"so I set up a port redirector on the demo server and pointed demo:143 to production:143 and fired up IMAP on 8.22 " Gordon. ---------- Original Message ---------------------------------- From: "Doug Traylor" <[EMAIL PROTECTED]> Reply-To: [email protected] Date: Fri, 3 Feb 2006 17:03:56 -0600 >The list has gone quiet for a little while so I thought I'd pipe up.
