As you see above, my emails are not going to the internal users, They are able to send, but ot able to receive.
In the SMTP Receiving log it shows up like: Reject relay to …
Anybody able to help me?
This is what I get from MXToolbox:
Connecting to 126.96.36.199
220 sendmymail.nl [735 ms]
250-PC-Monique Axigen ESMTP hello
250-AUTH PLAIN LOGIN CRAM-MD5 DIGEST-MD5 GSSAPI
250-AUTH=PLAIN LOGIN CRAM-MD5 DIGEST-MD5 GSSAPI
250 SPF check for <keeper-us-east-1c.mxtoolbox> returned no results [779 ms]
250 Sender accepted [1242 ms]
550 Relay denied for [726 ms]
I suspect it is this setting:
When I disable Require Authentication, the user is able to receive, and NOT able to send.
If I disable this, the the user is able to send and is NOT able to receive.
PS, I had to remove some .com’s from the text (2 links per post policy).
