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.
