emails send from eM client failing with ““Your message wasn’t delivered because the recipient’s email provider rejected it.””
with reason ““Remote Server returned ‘550 5.7.520 Message blocked because it contains content identified as spam. AS(4810)’””.
this problem happens when sending emails to diff. destination.
do any have any suugetion to solve the problem?
I encountered one of those bounce messages yesterday (not the exact same but a variant). I usually get this a few times a year and it will reference my email providers IP address. I would normally contact my email provider and they handle it.
I have not done anything about the current bounce as yet but will give it some attention later today as this so far is a one off.
Who is your mail provider and what DOMAIN were you sending to?
Some servers will reject messages as spam when the message has a signature.
If you have configured eM Client with signatures, try disabling them and see what happens.
