Attachment filter for Sendmail Milter

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.
