Truecommand hostname to send mails

[Urbaman]

Hi,

I'm trying to properly set the smtp mail protocol on truenasscale to send notifications and alerts.
Already done it without problem on TruenasSCALE, the way truecommand works seems not to use a proper valid hostname.
I installed truecommand on docker ina debian vm, the TrueNAS scale nodes are also VMs on nthe same hypervisor.

Where can I set truecommand's hostname and sqy to use it when sending mails?

Thank you very much
