SYNOPSISnoattach [-hn] [-p portinfo]
DESCRIPTION

regular expressions in a given pattern file and rejects those emails that
match.
Filenames are rfc2047 or rfc2231 decoded if needed.
The options are as follows:
-h Display a short help with commandline options.
-n Makes the program stay in foreground, i.e. don't fork into
the background and don't update the pid file
-p portinfo
The port to listen to
EXAMPLES
Listen to ipv4 port 26 on localhost:
noattach-p inet:26@localhost
Listen on a unix socket:
noattach-p local:/var/run/f1.sock

Information about the parameters for INPUT_MAIL_FILTER is in the
