+<p>This is held in the filename pointed to by the
+configuration option Filename rules. It contains a set of
+rules that are used to judge whether any given file
+attachment should be accepted or rejected on the basis of
+its filename, regardless of whether it is found to be
+virus−infected or not. This can not only be used for
+draconian measures such as banning all .exe attachments, but
+it can be used with any Perl regular expression to provide
+facilities such as detection of attempts at hiding
+filenames.</p>
+<!-- INDENTATION -->
+<p>Many Windows e−mail programs (eg. Microsoft
+Outlook) hide common file extensions in an attempt to not
+baffle the user. The result is that while an attachment
+called "Your Document.doc" is helpfully displayed
+as "Your Document", a more sinister attachment
+just as "Looks Safe.txt.pif" will appear simply as
+"Looks Safe.txt". Many users recognise the .txt
+filename extension as applying to plain text files, which
+they know are safe. So even an experienced user may well
+double−click on this attachment thinking it is just
+going to start Notepad and display the text file. However,
+the file is really an MS−Dos shortcut (.pif file) and
+can execute any arbitrary commands the author wanted: all
+without any indication to the unwitting user.</p>
+<!-- INDENTATION -->
+<p>The rules are matched in order from the top to the bottom
+of the file, and the first rule containing a matching
+regular expression is used. Each line of the file is either
+blank, a comment (in which case it starts with a
+’#’ character) or is a rule made up of 4 fields
+separated by one or more TAB characters:</p>
