      I've spun a new test server up on upcloud. While compiling php; which is hammering the cpu, I'm getting the expected lfd load alert.
    However I'm also getting a mail failure for
    Code:
    -r@hostname.domain
    where hostname and domain are valid. I do get one for the alert to my main mail.

    The LF_ALERT_TO = is set to my email address.

    It's the -r bit that's foxing me. I've checked .forward and other places where email might be set, I've grepped for -r in case I have botched exiting vim somewhere.


    It's not the end of the world, just confusing as :)

    Any thoughts?

    Is this a separate email from lfd high cpu alert or the same email ? If it's separate, what's the email subject name/title ?

    It's this one:
    Code:
    Subject: lfd on hostname.domain.tld Centmin Mod Extended Load
    Code:
    Final-Recipient: rfc822; -r@hostname.domain.tld
    Original-Recipient: rfc822; -r
    Action: failed
    Status: 5.1.3
    Diagnostic-Code: X-Postfix; bad address syntax
    All normal lfd mails, login etc are fine.

    Ah that email subject title is for Centmin Mod's csf_loadalert function which configures /etc/csf/csf.conf setting for PT_LOAD_ACTION to call /etc/csf/load.sh script when cpu load average is greater than the number of cpu threads you have on the server and sends additional server info from cminfo top and cminfo netstat commands which are defined in /etc/csf/csf.report. Looks like a found an additional bug in that /etc/csf/csf.report isn't properly emptied after each run (so will fix that).

    contents of /etc/csf/load.sh is taken from /usr/local/src/centminmod/config/csf/load.sh - see centminmod/centminmod

    The load.sh script defines a from email with -r populated by variable $CHECK_LFEMAIL which is populated via command
    Code (Text):
    awk -F '=' '/LF_ALERT_TO/ {print $2}' /etc/csf/csf.conf | sed -e 's|\"||g' -e 's|\s||'

    what's output for that command for you ?
