Please explain to me how the Cyurs imap process knows which realm to authenticate from if you are differentiating each domain by IP address?
I said (somewhat paraphrased): You cannot have 2 userid's named "chris" in the same Cyrus installation, without using 1 IP address per domain and that there is nothing more to say about it. You either create unique IDs across the mailbox namespace, or you burn 1 IP address per domain. If you can some how burn less than 1 IP address per domain I'd love to hear about it. If you were simply commenting that you can have one master, and multiple different imapd configurations, launched using the -c parameter, then our definitions of multiple Cyrus solutions is slightly different. I consider each authentication database/mailstore a separate Cyrus installation and perhaps that was our misunderstanding. -- Michael -- On Mon, 2001-10-08 at 04:52, Kevin M.
