TITLE
E-mail messages not delivered to external server even when local postoffice is disabled
PRODUCT, VERSION, OPERATING SYSTEM, ARCHITECTURE
Plesk 18.0.69, Windows Server 2025, MailEnable
PROBLEM DESCRIPTION
I have multiple domains hosted on my Plesk server. One of these has its mail service set to "Disabled", as its mail is handled externally. According to this support page, that should be enough for messages sent from another local domain using the local mail server to be sent to the external mail server, instead of being attempted to deliver locally.
However, I found that is not the case: such messages would not arrive. Only setting the mail server to "Not configured", removing the postoffice from MailEnable entirely and removing all existing mailboxes and messages (not an issue in my case, but I imagine other use cases where old mailboxes should be preserved) fixed this. I believe this should be fixed, or at least, the support page updated accordingly.
STEPS TO REPRODUCE
- Set up domain X with its mail DNS records pointing to an external e-mail server, and the local mail service for this domain "Disabled".
- Set up domain Y as default with local mail.
Send an e-mail message from domain Y to domain X.
ACTUAL RESULT
Message arrives on external mail service
EXPECTED RESULT
Message does not arrive anywhere
ANY ADDITIONAL INFORMATION
Other details to note: I use the SmartHost option to route outgoing e-mail. That may be relevant, although I don't believe it should affect this.
