Announcing mailfront version 0.96

Version 0.96 of mailfront is now available at:
	http://untroubled.org/mailfront/
------------------------------------------------------------------------------
Changes in version 0.96

- Switched Pattern matching from the simpler mechanism (originated in
  multilog) to standard shell glob.

- Fixed the SMTP front-end's inability to handle quoted or escaped
  characters, or to strip source routing addresses.

- Fixed smtpfront-reject crashing on receipt of EHLO.
  Thanks Janos Farkas.

- Fixed extern/static conflict in smtp-respond.c.  Thanks Gerrit Pape.

NOTE: The pattern matching change has the (small) potential to break
existing rules' behavior, if the rules were depending on specific
behavior of the more simplistic pattern matching used previously.

Development of this version has been sponsored by FutureQuest, Inc.

mailfront
Mail server network protocol front-ends
Bruce Guenter <[email protected]>
Version 0.96
2005-07-11

This is mailfront, a package containing customizeable network front-ends
for mail servers.  It contains complete SMTP, QMQP, QMTP, and POP3
front-ends as well as an authentication module for IMAP.  The mail
delivery front-ends also contain internal address filtering features.

Two SMTP back-ends are provided.  One delivers mail to qmail-queue,
mimicking most of the behavior of qmail-smtpd, with the addition of
support for SMTP AUTH.  The other rejects all SMTP commands if
$SMTPREJECT is set, and execs its command line otherwise (in order to
run the above program).

A mailing list has been set up to discuss this and other packages.

Development versions of mailfront are available via Subversion at:
	svn://bruce-guenter.dyndns.org/mailfront/trunk

Requirements:

- bglibs version 1.022
- cvm version 0.71

Installation:

- Build the sources by running "make"
- Run the "instshow" command to see what will be installed (optional).
- After the package has been compiled, run the following commands as root:
	./installer
	./instcheck
  These commands will produce no output if there are no errors.

Configuration:

- To take advantage of the SMTP AUTH features, make sure you have a CVM
  authentication program (some are included with the cvm package itself).
- Run a CVM authentication module to provide the AUTH feature.
  Example:  To run cvm-vmailmgr as a daemon:
    exec /usr/local/bin/softlimit -m 9000000 \
     /usr/local/bin/cvm-vmailmgr /tmp/.cvm-vmailmgr 2>&1
- Configure your mail system to use the SMTP back-end with the
  appropriate environment variables.

  Example using tcpserver (highly recommended):
    #!/bin/sh
    QMAILDUID=`id -u qmaild`
    NOFILESGID=`id -g qmaild`
    MAXSMTPD=`head -1 /var/qmail/control/concurrencyincoming`
    if [ -z "$QMAILDUID" -o -z "$NOFILESGID" -o -z "$MAXSMTPD" ]; then
        echo $0: QMAILDUID, NOFILESGID, or MAXSMTPD is unset
        exit 1
    fi
    exec \
    /usr/local/bin/envdir /etc/smtpfront \
    /usr/local/bin/softlimit -m 2000000 \
    /usr/local/bin/tcpserver -v -R -H \
      -l "`head -1 /var/qmail/control/me`" -x /etc/tcp.smtp.cdb \
      -c "$MAXSMTPD" -u "$QMAILDUID" -g "$NOFILESGID" 0 25 \
    /usr/local/bin/smtpfront-qmail 2>&1

  /etc/smtpfront/CVM_SASL_PLAIN:
    cvm-local:/tmp/.cvm-vmailmgr

  Example using xinetd with TCP Wrappers:

  /etc/xinetd.d/smtp:
    # default: on
    # description: smtp
    service smtp
    {
    	disable	= no
    	flags		= REUSE NAMEINARGS
    	socket_type	= stream        
    	protocol	= tcp
    	wait		= no
    	user		= qmaild
    	server		= /usr/sbin/tcpd
    	server_args 	= /var/qmail/bin/tcp-env -R /usr/local/sbin/smtpfront-wrapper
    	log_on_success          += USERID
    	log_on_failure          += USERID
    }

  /usr/local/sbin/smtpfront-wrapper:
    #!/bin/sh
    CVM_SASL_PLAIN=cvm-local:/tmp/.cvm-unix
    export CVM_SASL_PLAIN
    CVM_SASL_LOGIN=cvm-local:/tmp/.cvm-unix
    export CVM_SASL_LOGIN
    exec /usr/local/bin/smtpfront-qmail 2>> /tmp/smtpfront-errs.txt
