Problem virtualmin + spamassassin + procmail

If Ubuntu Server after you install and configure webmin + virtualmin there appears the error:

The procmail procmail command has 0 permissions, When It Should Be setuid and setgid to root. Email May Not Be Properly Delivered or checked for spam.

You can fix by following these steps:

1. Verify that the configuration files of postfix / etc / postfix / main.cf contains the following line:
   mailbox_command = / usr / bin / procmail-a "$ EXTENSION"
   if it appears: mailbox_command = procmail-a "$ EXTENSION" should be amended with the absolute path as above.
2. Change the group membership of / usr / bin / procmal from "mail" to "root." Chgrp root / usr / bin / procmail
3. Finally, set the following permissions procmail executable: chmod 6755 / usr / bin / procmail

Here are some links from which to get ideas for a better series, but in my case, these three steps to solve the problem, tested on Ubuntu Server 4.10 and 10.10.
