Hi,
We have some devices that need to email reports to us. It works with a comcast email /smtp . But when I put the info from our IRedMail server into it it doesn't work, the only thing I can see in the log I have pasted below, but it doesn't look very helpful (to me anyway....) If you have any ideas on how to bypass this so it works, please let me know.
