Plesk customer email issue

AlpineHost · Thursday at 7:49 AM

Hi all,

I have a customer in the US that is receiving a "host relay3.domain.com[IP Address] refused to talk to me: 554 relay3.domain.com" error on emails sent to his US Government email address and a few other domains, from our Plesk server. We have done an IP check on our side and we are all good, no blacklisting anywhere. SPF, DMARC and DKIM records are all confirmed to be correct. What will be the next step to check? Or, is this something that the customer needs to figure out on his own?

Thank you guys in advance for the feedback.

yes, ask the client to check his/her ip weather it is blacklisted , these things nowadays happens a lot, as all servers are protected by WAF firewall and securing their servers

Until you provide the complete failure email logs, we can just spekulate. Hide the details in the failed returning logs and provide it.
