Hi all,
Looking for some help with configuring email notifications from my PVE and PBS servers, but running into email errors.
Notifications have been configured via the GUI, as pictured below.
Test notifications come through just fine, and look as intended. Actual notifications from vzdump come into my inbox with the error noted far below AND the intended message content. Confirmed that the root user has the correct email address associated with it. If I had a static IP, this might be an easy fix, but as an enthusiast user with a dynamic IP I’m unsure how to proceed.
My UNRAID device has the same exact configuration and works just fine, so I know it’s a valid configuration. I’ve done some researched on the issue and haven’t been able to find a clear answer. Please advise.
