E-Mail 550-5.7.25 Error

[SCC Grup]

Hi guys!

When I try to send an e-mail with an account on my vps server, which has more than one account, I get the following error. The fact that the recipient is GMAIL doesn't change anything. Even if the e-mail is sent to another account on the same server, it still gives this error. I never understood what happened. It happened at once. Very happy if you help.

here e-mail recipient [email protected] (It also runs on the same server as ccholdig.com.tr.)

Hey there! Even when you're sending a message locally, something is still triggering a message to Gmail or else that wouldn't appear. Do you have any filters or forwarders configured on the system that would be sending to a Gmail address?

Yes, I was surprised by that too. How can I check this?

Inside cPanel you'll have two options - one for Global Email Filters and Email Filters, so that would be the first place I'd check.

I checked both on cPanel but it was completely blank. Is there anywhere else I can check? I can also access the WHM panel.

If you have root access to the server, I'd start by checking the mail log in /var/log/exim_mainlog so you can see the full email transaction as the server handles that message. That can often offer a clue as to why the behavior is happening.
