s3c0ndsky: +1! And no replies to this question since 2009... Did you find the/another solution? @Others: I Googled for days, weeks to find a -simple- solution for this. Using SASL rimap option, where multiple imap servers where users/domains reside are tried to authenticate. Or where we can provide domain:server mapping on where to authenticate users of which domain. We have several shared hosting servers that we want to keep isolated, but provide a central secure outgoing smtp server (including 587 submission port with an official certificate etc. to satisfy out-of-the-box security measures of the latest mailclient versions) that can be used by authenticated users from those different servers. Any simple alternative to achieve the same goal, without setting up a bunch of extra (complex) services and/or connections between these servers is also no problem. We already have a basic system in place that generates domain:server mappings (for central dns management).
