So while trying to figure out why my voicemail email notifications were sometimes taking a while to be delivered I had a go at disabling ipv6 - big mistake.
Google can be dangerous sometimes!
I added the following lines to /etc/sysctl.conf:
net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.default.disable_ipv6 = 1
On restart I’m now getting “unknown output from mailq” in the Dashboard.
I undid the changes and still get the same error.
So now I checked /etc/exim4/exim4.conf.template
Under MAIN CONFIGURATION SETTINGS
I see that ‘queue_list_requires_admin = false’ is there.
I ran update-exim4.conf anyway as I’d added this line and got an error stating it was duplicated.
Not sure why the error won’t clear but it’s driving the OCD in me nuts.
On restarting I get emails from Fail2Bin, and if I leave voicemails I do get the email notifications.
Can anyone help me with my OCD and help get rid of that annoying red warning?
