550 #5.1.8 Domain of sender address does not exist

Good Evening,

 

I am an owner of a small business and I am having difficulties sending emails to plusnet users.

The error is below - I have checked my MX, CNAME A and other email records and I cannot see any issue with them. 

I am not a plusnet customer myself, but this issue has me concerned enough for my customers as they are not receiving any order emails, and I have no other means to contact them which comply with GDPR. 

Any assistance is appreciated.

 

Kind Regards,

Steve

Hi Steve.

Apologies for the delayed response and thanks for reaching out to us here.

Unfortunately as @maidbloke has said it's something we're aware of and working to fix.

Please accept my apologies for the inconvenience caused in the interim.

From 31st October 2022, I no longer have a regular presence here as I’ve moved on to a new role.
