NAME

noattach —

scan email messages for bad attachments

SYNOPSIS

noattach [-hn] [-p portinfo]

DESCRIPTION

Noattach is a milter that parses the body of email messages from sendmail(8) and checks if the filename of attachments matches one of the 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

You also need to add INPUT_MAIL_FILTER to the .mc file you use to make the sendmail.cf.

Information about the parameters for INPUT_MAIL_FILTER is in the README.libmilter file wich is in the source tree.
