Sending mail

The server sends email for login codes, password links, alarms, update notices and the emergency access. Delivery is set up at the first login. You can change it under System Administration → Mail delivery.

Settings

Field	Meaning
Sender address	The address the emails come from
Delivery method	the host’s sendmail or SMTP server
SMTP host, SMTP port	SMTP only
SMTP user, SMTP password	A password left empty stays unchanged
Encryption	STARTTLS, SSL/TLS or none

After saving, send a sample with Test mail. Only when it arrives does the status change to tested, works. Some features, such as email as a second factor, require verified mail delivery.

Use a dedicated sending account

The SMTP password is stored unencrypted in the server’s database. Encrypting it would be pointless because the key would have to sit right next to it. So use a dedicated sending account, not your private mailbox.

Who receives which email

Email	Recipients
Login code, password reset	the address of the user concerned
Alarms	the recipients of the respective alarm rule
Update available, update installed	all owners
Emergency access	only the administrator address from config.php

If mail delivery is fixed in config.php, the fields here cannot be changed. The page indicates this with a notice.
