The title about says it all.
I getting email backing up.. it seems to still be flowing same, but I have to help by deleting spam. I look to see if I can find an issue and in the /var/log/maillog I find this....

warning: connect to Milter service local:/var/run/milter-greylist/milter-greylist.sock: Permission denied

I tried to turn off the greylist and it still is giving that error. So I turn it back on..

It sounds like a permission error, but I don't know where to look. The sock looks okay to me,

ls -l /var/run/milter-greylist/milter-greylist.sock

srwxr-xr-x 1 grmilter grmilter 0 Apr 17 00:50 /var/run/milter-greylist/milter-greylist.sock

service postgrey restart makes a new sock.

I will create, Remote Login Privileges as soon as this finish this and get a ticket number.

Okay, HELP. I have been using Virutalmin about 10 years. Very few times have I had to ask for help, but at this point I don't know what to do.. Thanks Don

Howdy -- the error you're seeing is actually related to the service that handles email rate limiting (I know the name is misleading... we didn't name it though :-)

You could always try restarting the milter-greylist service. But alternatively, we can try disabling it from Postfix altogether in order to get things back up and running.

What is the output of this command:

postconf -n

Is this really a "Permission" issue? I restart postfix,postgrey, the server!
It seems to be doing better but still getting the messages... Thanks.. Don

The issue isn't with postgrey or postfix, but with milter-greylist.

What you may want to do is edit /etc/postfix/main.cf, and comment out the lines beginning with "smtpd_milters" and "non_smtpd_milters". After that, restart Postfix.

Once you do that, do those errors stop?

But what did that do.? If the "greylist" working..? I see the milter-greylist still has a process running.
Thanks Don

Well, as described above, that's not related to greylisting (despite the name).

My goal for at the moment is just to get Postfix back up and running, so that email functions for you.

After commenting out the lines above, and restarting Postfix, do the errors stop, and are you then able to send and receive emails?
