I noticed an incoming email from a new domain (SPF and DKIM are all set up) has been rejected by mxroute.com:
host ocean dot mxroute dot com [195 201 59 214] said: 550
“The mail server detected your message as spam and has prevented delivery.”
(in reply to end of DATA command)
Since it’s no more possible to actually open a support ticket at mxroute.com user panel, how shall I handle this?
