Cyrus administration problem

[Nybbles2Byte]

Thanks but I am not sure how you are getting that conclusion from this wording in the manual.  As far as I can see it almost (but not quite) the reverse of what you are saying.

Configuring Virtual Domains
Introduction

Virtual domains is the practice of hosting a service for more than one domain on one server. Cyrus IMAP has the ability to host IMAP/POP mailboxes for multiple domains (e.g. test at example.com and test at example.net) on a single server or Murder.

In order to accomplish this, Cyrus needs to know which domain to look in when a mailbox is accessed. There are two ways in which Cyrus can determine the domain:

    * Fully qualified userid - the client logs in with a userid containing the domain in which the user belongs (e.g test at example.com or test%example.net)
    * IP address - the server looks up the domain based on the IP address of the receiving interface (useful for servers with multiple NICs or using IP aliasing)

Both of these methods are active if the virtdomains option is set to on (or yes, 1, true) and can be used in conjunction with one another. If the virtdomains option is set to userid, then only the first method is used. Note that a fully qualified userid takes precedence over a domain obtained from the IP address.
