but you can pastebin the rejected msg if possible then ask how to make that

Pardon my ignorance, but is pastebin an external site for this sort of
thing?
However, I'm not seeing rejected messages. I'll just get a call from
one of my clients saying they're not getting email. I'll send a test
message to them, and see this in the maillog:

for your own domains, start with spf / dkim / dmarc
and then only accept spf pass in mta stage, from that point you can begin
whitelist if needed, but keep the whitelist in spf since a single ip can have
a million domains :)
I'm sorry, this is the "beyond my level of expertise" that I was referring to.
