Hello Jeroen, I had prefer to deliver email twice main and backup machine and then use resyn to dele emails users had deleted from their client email.
In /usr/local/etc/postfix-out I have a file transport # TRANSPORT(5) Domain2.com smtp:[xxx.xxx.xx.xx] Domain3.com smtp:[xxx.xxx.xx.xx] Domain4.com smtp:[xxx.xxx.xx.xx] I would like to deliver to backup machine as well; could it be done?

The solution to increased load is not to store all email twice, as this will lead to insurmountable problems sooner rather than later. Consider deleting and/or moving messages, what goes where ? Are these IMAP backends then both synced with each other too ? If not, the next time Joe Q. connects to the other server, his email is all messed up - good luck explaining THAT to the users. If they are, why not deliver to one and sync to the other in the first place? Proper solutions focus on distributing different user accounts to separate storage backends (note that IMAP server != storage server), or scaling up your IMAP solution by, for instance, separating storage from the IMAP frontend(s). Postfix should deliver each message exactly once, so that the task of distributing the mail falls squarely on the chosen mail store solution (which can be very varied, but is never postfix). -- J. ----- No virus found in this message.
