ListProc will Reject the following words/commands
April 2004

Here is the list of words from the listproc source code. These are all regular expressions, so
the [ \t]+ in the middle means "one or more spaces or tabs".
A "^" character means that what follows must appear at the beginning of the line,
and a "$" character means that what preceeds must occur at the end of the line. Otherwise the pattern will match anywhere in the subject.

There's also a list of things that it will look for in messages that will cause it to assume you meant to give it commands (instead of send mail to the list) that will cause it to go into command processing mode (and not send your message to the list):
(^[ ]*Q?U?I?E?T?[ ]*ADD[ ]+([A-Z0-9.@-]+)[ ]+.+[ ]+.+)
(^[ ]*HELP[ ]*[A-Z0-9]*$)
(^[ ]*RECIPIENT?S?[ ]+([A-Z0-9.@_-]+)[ ]*.*$)
(^[ ]*SUBSC?R?I?B?E?[ ]*([A-Z0-9.@_-]*))
(^[ ]*SIGN?O?F?F?[ ]*([A-Z0-9.@_-]*))
