NAME

       mailfilter - Filters e-mail, gets rid of spam

SYNOPSIS

       mailfilter [OPTION]...

DESCRIPTION

       Mailfilter  is a very flexible utility to get rid of unwanted spam mails, before having to go through the
       trouble of downloading them into the local computer. It offers support for one or many POP  accounts  and
       is especially useful for dialup connections via modem, ISDN, etc.

       Mailfilter  connects to any POP mail box and compares part of its content to a set of user defined filter
       rules. That way the spam gets deleted directly on the mail server.

       With Mailfilter you can define your own filters (rules) to determine which e-mails  should  be  delivered
       and  which  are  considered waste. Rules are Regular Expressions, so you can make use of familiar options
       from other mail delivery programs such as procmail(1) for example.

RETURN VALUE

       The mailfilter program normally returns 0 but -1 if an error occurs.  However, if  it  has  been  invoked
       with the return-value command line switch, it gives back a positive integer in case there are messages on
       the  POP  server.   Empty  POP  accounts  would  then  result  in a return value of 0.  Using the switch,
       mailfilter can be embedded into a shell script more easily.

CONFIGURATION

       The behaviour of Mailfilter is controlled by command-line options and a configuration file.  The  program
       will  not  start  without it. Example configurations can be looked up in the mailfilterex(5) man page, in
       the INSTALL document or inside the doc/ directory of the Mailfilter distribution.

       By default Mailfilter tries to read $HOME/.mailfilterrc to get all its settings from. This is  the  place
       where  all  changes  should be made, unless it is explicitly specified otherwise. A comprehensive list of
       all supported options and keywords can be found in the mailfilterrc(5) man page.
