I have a domain xxx.com in a server that has allot of users. And then i have a server in the office with exchange 2013 that has about 5 users and uses the same domain xxx.com. What is happening is when thos 5 users try to send and email to a user out of the exchange server in the same domain xxx.com, we get a email error that the user was not found, wll that is normal. What i need is, if the user account doesen’t exist in the exchange server, so send it to another email server in the outside. how is that possible ? I’m using a pop collector to colect the emails form the outside server of domain xxx.com into the exchange server. Dont have a fixed ip address, and use a smtp connecto to send out the email. Thanks Allot Kevin OssianModerator October 22, 2016 at 10:44 am #191405 You need to create a “relay domain” (internal or external depending on requirements, but from the above probably external) More info: https://technet.microsoft.com/en-us/library/bb124423(v=exchg.150).aspx Author Posts Viewing 2 posts - 1 through 2 (of 2 total) You must be logged in to reply to this topic.
