Sending mail from inside the LAN to Exchange 2013 server
Posted on 2014-02-07
Trying to get our Exchange server to send mail received from a 3CX server (on the same LAN). Can't seem to get it to work, even though a multi-function printer on the same LAN is able to send emails out using the same mail server.
Not sure if I am possibly entering the credentials wrong or what, and have not been able to get anything useful from the Exchange log file - there's stuff in there that seems relevant (based on the source address), but I have no idea what it means...
Anyone have any idea how to interpret these logs? Are there utilities out there that help with this?
Any suggestions as to what I could do to further problem-solve?
