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.
