Emails being blocked despite white list

[#1]

My emails from admin@slotracer.online are being blocked despite being included on my white list. Also, if I include a link to that site in an outgoing email it gets rejected as spam and not sent.

I have had the same problem with other perfectly safe sites in the past, are Plusnet's filters out of control?

Hello @CMOTD,

Thanks for reaching out to us here and apologies for the delayed response.

I'm sorry you are having trouble with sending & receiving emails, are you utilising a client application or webmail when you are trying to send or receive these emails?

Thanks.

Hi @CMOTD, just to follow up on this can you send me over a PM with the email headers and bounce back rejection and I'll get this passed to the relevant team to look at for you.
