I dont think my cpanel servers are properly serving RCPT TO responses. My anti-spam gateway is supposed to check with my cpanel server to see if an account exists before it attempts delivery, but its accepting mail for accounts that do not exist and then my cpanel server is doing the bounce to accounts that dont exist. Where should i be looking into this on the cpanel server? I do have gateways whitelisted for sender verification, but I wouldn't think that would have anything to do with the actual recipient existing or not. Thoughts? Email is being delivered in general just fine form my gateways to my cpanel servers, but I definitely need to make sure my gateways are bouncing the emails and not the destination servers. I am not really sure where I should be doing to properly test it and fix the configuration within cpanel if its wrong.

Hello :)

It seems like it might be an issue with your SPAM gateway server if that's where the bounce is failing to occur. Have you checked with the support of the specific software you are using to see if there are any configuration values that should be changed?

Thank you.
