Hello guys, I have a Postfix problem (I think). Mails go out fine to most domains. However in the last week I have seen my customers complain that mails sent to people at two domains are bouncing. See below for the bounce message.

I have a PTR for my domain. I also have an SPF for my domain.

I have searched world-wide :slight_smile: for an answer but no use.

Any help is much appreciated and you guys have already helped me in the past and for that thank you.
