Not true for Exim provided that both the virtual servers are using the same IP address (as you have stated that they are). Independent of the domains, Exim sorts outgoing addresses according to the host lists they route to, and uses a single connection for those that are going to the same hosts (up to the max_rcpt limit, and subject to having the same added headers, rewritten return-path, etc, etc. that is, when the message bodies are identical). -- Philip Hazel University of Cambridge Computing Service Get the Exim 4 book: http://www.uit.co.uk/exim-book -- ## List details at http://www.exim.org/mailman/listinfo/exim-users ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://www.exim.org/eximwiki/
