Thank you for the report, .

The comments in the Topic:
The new UI concentrates e-mail into 3 places, from what I've seen.

1. Root's e-mail address, under Accounts->Users. From what I can tell, this is only used for OS-level alerts, which should be very rare.

2. System->Email, which defines the external mail settings.

3. System->Alert Services->Email. If this is blank, it will use the setting from 2.

Jails and plugins need to have their e-mail set up individually.

An I correct that the only SMTP settings are in 2 System->Email?

It's the smtp setting I am worried about because I have only changed smtp provider, not the addresses/domain.

IIUC the only place that I would need to change is 2 System->Email - Correct?
-----------------
 
Correct. System->Email is the only place to define external SMTP parameters.

While UPS triggers are covered under System > Alert Settings, there's still an email field under Services > UPS. It's unclear whether this is defunct now, or whether it still needs to be configured? If it's defunct, it should really be removed from the latter to avoid any ambiguity.
