So I’m using my third party mailbox service, to use the domain email system. However, all my domain email got this error whenever I try to send or test to receive for any email… I already turn off the bouncy message, but I still receive this error…
When I’m still using namecheap this never happends until I send my DNS to Cloudflare to use the CDN.
I just tested a couple of minutes ago from my end, and it looks like I can send message(s) just fine to that address quoted, … did you receive anything from @darkdevil.dk?
“Relay access denied” is indicating that the mail server you connect to, has not been configured to accept messages for the given domain.
For example, if you set your MX records to point to Google’s mail servers, and that Google’s mail servers aren’t set up to be accepting messages directed to your domain, Google would respond with that specific code/message to other mail servers that are attempting to make deliveries.
The SMTP sever you use to send your messages with, can also refuse to accept messages, with the Relay access denied message see, which would most often be because the email client you use, isn’t authenticating properly with the mail sever, and try to relay (“send”) messages over the server, without authenticating (e.g. with username+password) first.
Various email clients have different ways of how to enable SMTP authentication, so that part can be adjusted, would be something you need to take up with the documentation of your email client.
The error message in this screenshot is however different, and not directly related to the error above, and claims “550 5.7.1 [CSR] Our system has detected an unusual amount of unsolicited email originating from your address. Contact your service provider for support”
Since the server named server1.saysheji.art that rejects the message, appears to be (have been?) running on Namecheap, as such, I would normally suggest to contact Namecheap for further assistance about that specific error.
That be, unless you rent an unmanaged server (e.g. dedicated server, root server, VPS, …), that you manage on you own, … in which case you would (obviously) need to figure out the things, on your own.
That said, → I would still start by following the advice from my previous message, about adjusting the Proxy status of the email related records to become Unproxied () / DNS-only, and see if that helps.
My apologies for the long delay. I have solved this issue weeks ago, the cause was one of my server domains has been spams for about 1000 messages, since the tremendous mail queue I was unable to send a message.
But now there’s another problem, I able to receive message from gmail, however I cant receive anything form my sites. I think its the Mail record problem that I set at my DNS record.
I actually try the third-party mailbox service with another domain, but the DNS is at Namecheap not Cloudflare which is euequities.io, it’s working. So, I was wondering maybe thaigood4u.com isn’t able to because it’s misconfigured at the Cloudflare.
