[quote user="karnel"] If all above correct - it looks like I need to get rid somehow of MercuryS and communicate to MercuryE directly. It should be done so that when outlook opens connection to MercuryE, try to send message over it, and wait for outcome.Only then outlook should receive either error either ok and can close connection to MercuryE. Or another option to force MercuryS not give any answer to outlook until it not received outcome from MercuryE and not passed it back to outlook.[/quote]
You can't talk to MercuryE directly. Below is the path a message travels
Outlook -> MercuryS -> Core -> MercuryE -> mx.host
An error is received when MercuryE talks to the foreign system, f.ex. recipient does not exist. This message is the one you need to get back, f.ex. by creating as Thomas says, a local user account under the domain localhost - but then your from will be bogus, or move the error report message via filtering rule. In order to retrieve this message you need to activate MercuryP, and set up a retrieve only account in your Outlook, that retrieves the message from the Mercury local user you just created.
