It would not. Postfix handles multipe IP addresses and/or MX hosts robustly. If multiple servers are equally good destinations for a message use either a logical DNS name with multiple IPs or equal weight MX hosts. If one server is better than all the rest, use non-equal weight MX records. -- Viktor. Disclaimer: off-list followups get on-list replies or get ignored. Please do not ignore the "Reply-To" header.
