There really isn't much to say, noattach is a milter that parses the body of email messages from sendmail 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. This program needs sendmail version 8.12.2 or newer to be compiled with libmilter. WWW: http://freecode.com/projects/noattach/
