    Remove DKIM selector

    Hi! I mean deleting a selector from the PMG configuration. I added a selector with an incorrect name by accident. I executed: root@mgw1-0:/etc/pmg/dkim# rm default.private root@mgw1-0:/etc/pmg/dkim# Are there any database records I should clean up or anything?

    How should a DKIM selector be removed? (Doesn't seem to be documented :) )

    pmgtunnel cannot use -L

    I rebooted all nodes in the cluster, promoted a slave to master, deleted the other slaves from the cluster, and re-added them. All nodes are in A again. Strange!

    Very High Load Average

    I don't think that's the right way to look at this. If you don't start with a normal setup, you're bound to run into issues at some point. Start by fixing your setup. You'll need to do that if it isn't the cause of your issues anyway :)

    unable to connect to localhost at port 10025

    Thanks Stoiko! I appreciate the quick fix. I did already try replacing '127.0.0.1' with '::1', but I will try your fix later today. The IPv4 connection is established through a proxy with a dual-stack frontend.

    SPF check for relayed mail

    When using PMG as an SMTP relay, I want the SPF check to be skipped for mail offered to the internal SMTP port; only the PMG servers are specified in SPF records, not the internal host using the PMG smarthost. I can of course add custom SpamAssassin rules for this, but before I do that, I'd...
