When a message is posted to the list, a series of moderation steps are taken to decide whether a moderator must first approve the message or not. This section contains the controls for moderation of both member and non-member postings. <p>Member postings are held for moderation if their <b>moderation flag</b> is turned on. You can control whether member postings are moderated by default or not. <p>Non-member postings can be automatically <a href="?VARHELP=privacy/sender/accept_these_nonmembers" >accepted</a>, <a href="?VARHELP=privacy/sender/hold_these_nonmembers">held for moderation</a>, <a href="?VARHELP=privacy/sender/reject_these_nonmembers" >rejected</a> (bounced), or <a href="?VARHELP=privacy/sender/discard_these_nonmembers" >discarded</a>, either individually or as a group. Any posting from a non-member who is not explicitly accepted, rejected, or discarded, will have their posting filtered by the <a href="?VARHELP=privacy/sender/generic_nonmember_action">general non-member rules</a>. <p>In the text boxes below, add one address per line; start the line with a ^ character to designate a <a href= "http://docs.python.org/library/re.html" >Python regular expression</a>. When entering backslashes, do so as if you were using Python raw strings (i.e. you generally just use a single backslash). <p>Note that non-regexp matches are always done first.

The topic filter categorizes each incoming email message according to <a href="http://docs.python.org/library/re.html">regular expression filters</a> you specify below. If the message's <code>Subject:</code> or <code>Keywords:</code> header contains a match against a topic filter, the message is logically placed into a topic <em>bucket</em>. Each user can then choose to only receive messages from the mailing list for a particular topic bucket (or buckets). Any message not categorized in a topic bucket registered with the user is not delivered to the list. <p>Note that this feature only works with regular delivery, not digest delivery. <p>The body of the message can also be optionally scanned for <code>Subject:</code> and <code>Keywords:</code> headers, as specified by the <a href="?VARHELP=topics/topics_bodylines_limit">topics_bodylines_limit</a> configuration variable.
