Building MIMEDefang

First you need to build Sendmail 8.12.8. Refer to building
sendmail document.

Prereques:

Modules:

IO::Stringy 1.211
http://www.roaringpenguin.com/mimedefang/IO-stringy-1.212.tar.gz

IO::Handle
Comes with Perl 5.8

Net::SMTP
Net::Domain

Mailtools
Mail::Field 1.05
Mail::Header 1.01
Mail::Internet 1.0203
http://search.cpan.org/CPAN/authors/id/M/MA/MARKOV/MailTools-1.58.tar.gz

MIME::Base64 2.11
http://search.cpan.org/author/JHI/perl-5.8.0/ext/MIME/Base64/Base64.pm

HTML::Parser
http://search.cpan.org/CPAN/authors/id/G/GA/GAAS/HTML-Parser-3.27.tar.gz

Perl-5.7 provide experimental core support for Unicode strings.  You
can compile HTML::Entities so that Unicode entities like € and
€ are decoded into a string containing "\x{20AC}".  If you
select no to the question below such entities will be left alone and
only entities in the Latin-1 range is decoded.

Do you want decoding on unicode entities? [no] (I answered no)

Anomy::HTMLCleaner

Build on admin server workbench

copy to wsadmin01:/build

# cd /build
# gzip -d mimedefang-2.31.tar.gz
# tar xvf mimedefang-2.31.tar
# cd mimedefang-2.31
# ./configure --prefix=/usr/local --with-milterlib=/build/sendmail-8.12.8/obj.SunOS.5.8.sun4/libmilter --with-milterinc=/build/sendmail-8.12.8/obj.SunOS.5.8.sun4/libmilter --disable-anti-virus

Make sure the following message appear from configure:

checking for Perl module IO::Socket... ok

*** Virus scanner detection results:
All virus-scanner detection disabled by --disable-anti-virus

Could not find any recognized virus scanner... do not use
any of the contains_virus functions in your filter.
Found Mail::SpamAssassin.  You may use spam_assassin_* functions
Found Anomy::HTMLCleaner.  You may use anomy_clean_html()
Found HTML::Parser.  You may use append_html_boilerplate()

Note: SpamAssassin, File::Scan, HTML::Parser and Anomy::HTMLCleaner are
detected at run-time, so if you install or remove any of those modules, you
do not need to re-run ./configure and make a new mimedefang.pl.

Note:  The MIMEDefang user 'defang' does not seem to
exist.  Please create this user before continuing.

Create defang account

(refer to the document Configuring Sendmail SpamAssasin and MIMEDefang on
how to setup the accounts and directories)

# make install

Now create the init script: /etc/init.d/mimedefang and put
the following lines:

#!/sbin/sh
#
# Startup init script for mimedefang

Before starting up MIMEDefang copy the configuration from either mail1 or mail2
from the following files:

/etc/mail/mimedefang-filter
/etc/mail/mimedefang-ip-key

Now to install MIMEDefang on another host from the one it was compiled on:

First of all if the above Perl modules are not installed you will need them
installed first.

Copy the following files to the remote server in the tmp directory:

# scp /build/mimedefang-2.31/mimedefang-multiplexor kinscoe@mail2:/tmp/.
# scp /build/mimedefang-2.31/md-mx-ctrl kinscoe@mail2:/tmp/.
# scp /build/mimedefang-2.31/watch-mimedefang kinscoe@mail2:/tmp/.
# scp /build/mimedefang-2.31/mimedefang kinscoe@mail2:/tmp/.
# scp /build/mimedefang-2.31/mimedefang.pl kinscoe@mail2:/tmp/.
# scp /build/mimedefang-2.31/mimedefang.8 kinscoe@mail2:/tmp/.
# scp /build/mimedefang-2.31/watch-mimedefang.8 kinscoe@mail2:/tmp/.
# scp /build/mimedefang-2.31/mimedefang.pl.8 kinscoe@mail2:/tmp/.
# scp /build/mimedefang-2.31/mimedefang-multiplexor.8 kinscoe@mail2:/tmp/.
# scp /build/mimedefang-2.31/md-mx-ctrl.8 kinscoe@mail2:/tmp/.
# scp /build/mimedefang-2.31/mimedefang-filter.5 kinscoe@mail2:/tmp/.
# scp /build/mimedefang-2.31/mimedefang-protocol.7 kinscoe@mail2:/tmp/.

On the remote server make backups of the production files:

# mkdir -p /usr/local/bin/old
# cp /usr/local/bin/mimedefang-multiplexor /usr/local/bin/old/mimedefang-multiplexor 
# cp /usr/local/bin/md-mx-ctrl /usr/local/bin/old/md-mx-ctrl
# cp /usr/local/bin/watch-mimedefang /usr/local/bin/old/watch-mimedefang
# cp /usr/local/bin/mimedefang /usr/local/bin/old/mimedefang
# cp /usr/local/bin/mimedefang.pl /usr/local/bin/old/mimedefang.pl
# chmod 500 /usr/local/bin/old/*

Install:

Stop sendmail on the remote server:

# /etc/init.d/sendmail stop

Stop MIMEDefang on the remote server:

# /etc/init.d/mimedefang stop

On the remote server move from /tmp to the production directory:

# mv /tmp/mimedefang-multiplexor /usr/local/bin/mimedefang-multiplexor
# mv /tmp/md-mx-ctrl /usr/local/bin/md-mx-ctrl
# mv /tmp/watch-mimedefang /usr/local/bin/watch-mimedefang
# mv /tmp/mimedefang /usr/local/bin/mimedefang
# mv /tmp/mimedefang.pl /usr/local/bin/mimedefang.pl
# mv /tmp/mimedefang.8 /usr/local/man/man8/mimedefang.8
# mv /tmp/watch-mimedefang.8 /usr/local/man/man8/watch-mimedefang.8
# mv /tmp/mimedefang.pl.8 /usr/local/man/man8/mimedefang.pl.8
# mv /tmp/mimedefang-multiplexor.8 /usr/local/man/man8/mimedefang-multiplexor.8
# mv /tmp/md-mx-ctrl.8 /usr/local/man/man8/md-mx-ctrl.8
# mv /tmp/mimedefang-filter.5 /usr/local/man/man5/mimedefang-filter.5
# mv /tmp/mimedefang-protocol.7 /usr/local/man/man7/mimedefang-protocol.7

Now fix the perl line in mimedefang.pl

Verify where the perl interprator is located:

# which perl
/opt/sfw/bin/perl

Edit /usr/local/bin/mimedefang.pl and change the line:

#!/usr/local/bin/perl -w

to

#!/opt/sfw/bin/perl -w

# chown root:other /usr/local/bin/*
# cmhod +x /usr/local/bin

Restart MIMEDefang on remote server:

# /etc/init.d/mimedefang start

Change the line in /etc/mail/sendmail.cf

sendmail.cf:Xmimedefang, S=unix:/var/spool/MIMEDefang/mimedefang.sock, T=S:5m;R:5m;E:5m

to

sendmail.cf:Xmimedefang, S=unix:/var/spool/MIMEDefang/mimedefang-multiplexor.sock, T=S:5m;R:5m;E:5m

If it is not already set that way.

Restart sendmail on remote server:

# /etc/init.d/sendmail start
