Hi all,
Since MS Exchange email servers need to add additional entry in proxyaddress of MS AD server, such as: "smtp: x...@exchange.xxx", in our previous configuration, postfix powered email servers are able to query the entries in the field of proxyaddress and relay email, but once the query result contains "smtp: x...@exchange.xxx", postfix will try to delivery with the username as "smtp: xxx" and then generate a user not found bounce email. I would like to ask is there any way to avoid the bounce? Thanks again for your time. Best, Jacky
