Webmin 1.690 Ubuntu Linux 10.04.2
I followed the advice on Webmin screen to auto-remove packages that are no longer required, and ran into trouble when I did a server reboot. Apache won't start, and more importantly procmail did not work because of missing procmail-wrapper, which I managed to fix by "apt-get install procmail-wrapper"
Now I have another problem. After checking the mail logs I noticed this:
warning: SASL authentication failure: cannot connect to saslauthd server: No such file or directory www postfix/smtpd: warning: xxxxx: SASL LOGIN authentication failed: generic failure
