Not receiving mail from specific address

maybl8

A mail was attempted to send to me and I didn’t get it.
If the postfix log I see this:
Not sure if my postfix is doing this or the senders server is doing this?

This is your postfix.
Milter is a plugin that enables clamav virus scanner or olify for macro virus checking.
Make sure that those services are running properly. Or maybe the mail contained a false positive?
You could also check clamav/olefy/rspamd logs.

This is what the rspamd log shows but I don’t know what it decided was wrong to reject it.

maybl8 dan.cihon@sbcglobal.net

Could it be that this is the sender?
He is using yahoo “freemail” servers (consumer servers) to send. Obviously thats not a good idea. I think he seems to have registered his domain with yahoo (after all this?), there should be different servers for business customers. Or he is using the SMTP relay with a wrong (consumer) account…

maybl8 If you want to dig deeper, here is the definition and what it contains

He has a sbcglobal.net account but it has been turned over to yahoo or att not sure.
I’ll have to see if I know anybody that has other yahoo accounts and see if they can send me mail.
I guess I could whitelist the email address?

Sure.
