I have run into an issue where the blocker was originally setup with an internal hostname. Now we have reconfigured it with an external one on the interface but when mail is being sent by the blocker it still gives the internal hostname as its HELO name.
I have rebooted the device with no luck.
Anyone come across this? We are getting mail bounced from some people due to HELO checks.
can you please check on the CLI with 'deliveryconfig' what your default delivery interface is and change the IP Interface hostname of it (either on the CLI with 'interfaceconfig' -> 'edit' or on the GUI with Network > IP Interfaces)? The system takes the IP Interface hostname as EHLO/HELO name when establishing outbound connections.
Thanks and regards,
