CSF/LFD not sending login emails for Webmin

[Starburst]

Using ConfigServer Security & Firewall 14.24

For some reason CSF/LFD isn't sending out emails notifications for Webmin logins.

SSH notifications work fine.
Se do email test from the CLI.

The option to send alerts is set to Enable: LF_WEBMIN_EMAIL_ALERT = 1

RESTRICT_SYSLOG is set to 3.

Any suggestion would help.

If you have MailScanner installed, look if those emails are not blocked as "high spam", if so, add the sender email to the white list.

MailScanner isn't installed.

SSH alerts from CSF/LFD are received OK.
So are other root emails form the server.

Server is running AlmaLinux 9.5

Are the emails that are not delivered saved under CSF MailQueues?

What directory would they be saved in?

Got a LFD firewall notification this morning of a SSH trigger.
