(Caveat: I've not touched Exchange in ages) Do you have the Recipient Filter enabled? http://technet.microsoft.com/en-us/library/bb123891%28v=exchg.150%29.aspx > Yes, I know, using cutthrough routing/delivery could partially > solve my problem.

Theoretically multi-recipient could be supported if both sides ran PRDR and exim could handle multiple concurrent outbound connections (for the multiple-recipient-domain case). Or if we gave up on rfc822 header processing, and store-forward for the temp-error cases... -- Cheers, Jeremy -- ## List details at https://lists.exim.org/mailman/listinfo/exim-users ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://wiki.exim.org/
