Only by IP or CIDR not by domain.

Is port 443 listed in the TCP_IN and TCP_OUT sections of the IPv4 and IPv6 Port Settings?

Are you using PSInsights from the Google Search Console or within a browser with Developer Tools?

Try removing port 25 from TCP_IN and TCP_OUT for both IPv4 and IPv6.

Likely seeing it as a double file extension.

Just a guess.

Sounds like a configuration issue with Messenger service.as the REDIRECT ports are the defaults listed in the csf.conf.

What root logins - SSH, su to root using SSH or WHM?

If "su", try setting LF_SU_EMAIL_ALERT.

Assume you've restarted CSF/LFD after making previous changes?

Add your IP to csf.ignore.

Assume you've confirmed your IP isn't in either csf.allow or csf.ignore?

Other thing I'd rule out is whether alerts are working if you change "root" to "all", restart CSF/LFD and try logging in with a cPanel user account.

UI_ALERT settings refer to the Integrated User Interface not cPanel/WHM logins.

Check that LF_CPANEL_ALERT is enabled instead.
