New fresh installation of Virtualmin on Centos 6.5 64bit, everything seems to be ok, except Postfix does not receive mail, error message is:
The error that the other server returned was:
451 4.3.5 Server configuration problem
and all the emails get delayed (not delivered).
Checked all settings - everything seems fine. How do I find out the problem? Or should I just reinstall the system again? In iptables SMTP/POP3 is all open for incoming
First step as always: Take a look at the log files in /var/log
, especially the syslog and mail log. Postfix should note any errors it encounters there.
ok, got the answer, it had something to do with the “greylist” package:
errors are:
“warning: connect to /var/spool/postfix/postgrey/socket: No such file or directory”
strange thing is postgrey package was installed, but no “postgrey” user was added to the system.
So I have fixed it by removing the package and installing it again.
Now everything seem to work perfect.
Thanks!
Glad you got it working, rock on!
