My thanks to all netizens who have helped me, especially Tony Nugent (email@example.com), David Summers (firstname.lastname@example.org) and S.u.S.E ( Linux distribution) who has made installing Linux so much easier, and the authors of the above excellent programs.
What is qmail and why should I use it? Here is the authorīs (Dan Bernstein) blurb:
qmail is a secure, reliable, efficient, simple message transfer agent. It is meant as a replacement for the entire sendmail-binmail system on typical Internet-connected UNIX hosts.
Secure: Security isn't just a goal, but an absolute requirement. Mail delivery is critical for users; it cannot be turned off, so it must be completely secure. (This is why I started writing qmail: I was sick of the security holes in sendmail and other MTAs.)
Reliable: qmail's straight-paper-path philosophy guarantees that a message, once accepted into the system, will never be lost. qmail also supports maildir, a new, super-reliable user mailbox format. Maildirs, unlike mbox files and mh folders, won't be corrupted if the system crashes during delivery. Even better, not only can a user safely read his mail over NFS, but any number of NFS clients can deliver mail to him at the same time.
Efficient: On a Pentium under BSD/OS, qmail can easily sustain 200000 local messages per day---that's separate messages injected and delivered to mailboxes in a real test! Although remote deliveries are inherently limited by the slowness of DNS and SMTP, qmail overlaps 20 simultaneous deliveries by default, so it zooms quickly through mailing lists. (This is why I finished qmail: I had to get a big mailing list set up.)
Simple: qmail is vastly smaller than any other Internet MTA. Some reasons why: (1) Other MTAs have separate forwarding, aliasing, and mailing list mechanisms. qmail has one simple forwarding mechanism that lets users handle their own mailing lists. (2) Other MTAs offer a spectrum of delivery modes, from fast+unsafe to slow+queued. qmail-send is instantly triggered by new items in the queue, so the qmail system has just one delivery mode: fast+queued. (3) Other MTAs include, in effect, a specialized version of inetd that watches the load average. qmail's design inherently limits the machine load, so qmail-smtpd can safely run from your system's inetd.
Replacement for sendmail: qmail supports host and user masquerading, full host hiding, virtual domains, null clients, list-owner rewriting, relay control, double-bounce recording, arbitrary RFC 822 address lists, cross-host mailing list loop detection, per-recipient checkpointing, downed host backoffs, independent message retry schedules, etc. In short, it's up to speed on modern MTA features. qmail also includes a drop-in ``sendmail'' wrapper so that it will be used transparently by your current UAs.
SuSE Linux Distribution 5.1 with 2.0.33 kernal.
PPP link to ISP
Follow the INSTALL instructions exactly.
Please take the time to read the Fine documentation completely. The numerals refer to the installation steps in the above INSTALL doc.
Dan Bernstein has provided a package for sending queued email to an ISP via dial-in. This package is available as serialmailxxx from his site.
Install this package as described in the man page (Thanks Rupert Mazzucco (email@example.com), it works out of the box!
maildir2smtp - blast a maildir across SMTP maildir2smtp is designed to pass messages along a SLIP or PPP link. To set this up on the disconnected end, create a new maildir in alias: # maildirmake ~alias/pppdir # chown -R alias ~alias/pppdir Put :alias-ppp into control/virtualdomains and ./pppdir/ into ~alias/.qmail-ppp-default. Don't forget the extra slash in pppdir/. Then, in the PPP startup script, do maildir2smtp ~alias/pppdir alias-ppp- $IP `hostname` replacing $IP with the remote IP address.
In addition to this, I also replaced /mh-6.8.4/mts/sendmail/smail.c with Dan Bernsteinīs mh-qmail-smail.c
This is what my mh-6.8.4/conf/MH looks like:
bin /usr/bin/mh etc /usr/lib/mh #mail #mandir /usr/man #manuals standard chown /bin/chown #cp cp #ln ln #remove mv -f cc gcc ccoptions -traditional -O2 -m486 -D_NFILE='getdtablesize()' -DSIGEMT=SIGUSR1 curses -lncurses #ldoptions -s #ldoptlibs lex flex #oldload off #ranlib on mts sendmail #mf off #bboards off #bbdelivery off #bbhome /usr/spool/bboards pop on popdir /usr/lib/mh sharedlib sys5 slflags -fPIC slibdir /usr/lib mailgroup mail signal void sprintf int #editor prompter #debug off #regtest off options ATHENA options BIND options DPOP options DUMB options FCNTL options MHE options MHRC options MIME options MORE='"/usr/bin/less"' options OVERHEAD options POP2 options POPSERVICE='"pop3"' options RENAME options RPATHS options RPOP options SOCKETS options SVR4 options SYS5 options SYS5DIR options TERMINFO options UNISTD options VSPRINTF
As qmail delivers mail to the home directory (~/Mailbox). I added the following to my mtstailor
localname: mickey localdomain: n.eunet.de mmdfldir: mmdflfil: Mailbox uucpldir: uucplfil: mmdelim1: \001\001\001\001\n mmdelim2: \001\001\001\001\n mmailid: 0 umincproc: lockldir: sendmail: /usr/lib/sendmail
Here is my .mh_profile
Path: Mail draft-folder: drafts unseen-sequence: unseen AliasFile: /home/rdn/.mh_aliases send: -msgid comp: -form /home/rdn/.mymh-components MailDrop: /home/rdn/Mailbox
I decided to use fetchmail because I have a multiuser (my family :). Linux and fetchmail delivers mail to the smtp port where qmail takes over.
Installation was no problem, multidrop works with the following .fetchmailrc :
poll PersonalMail.Germany.EU.net protocol pop3 username myname password mypassword # the next two lines do the trick for multidrop localdomains mydomain.de is * here # T2 of the fetchmail FAQ states that qmail needs this forcecr
This is my mailer by choice. I love it.
There is one problem - most pre-compiled TCL/TK packages have the security option compiled in. The following script .xserverrc.secure which came with SuSE solves this.
#!/bin/sh # # move this file to ~/.xserverrc, if you don't want to allow everybody to # get access to your X-Server # if [ -x /usr/bin/keygen ]; then if [ ! -x /usr/bin/hostname -a ! -x /bin/hostname \ -a ! -x /usr/bsd/hostname ]; then echo "startx: can't get my hostname - exiting" exit 1 else host=`hostname` fi xauth add $host:0 . `/usr/bin/keygen` sleep 2 xauth add $host/"unix":0 . `/usr/bin/keygen` exec X :0 -auth .Xauthority $* else exec X :0 $* fi
The qmail FAQ gives this command:
In /.qmail add the line
| preline procmail
Version 3.11pre7 has changed the default mail box variable. It used to be in config.h. It is now in src/authenticate.c:
#define MAILSPOOLHOME "/Mailbox" /* watch the leading / */ /* delivers to $HOME/Mailbox */
I have culled from comp.mail.mh ans comp.mail.misc some hints on a .procmailrc file. Thanks to everyone!

Procmail is an excellently documented program. Read the man pages for examples on how to set up your .procmailrc file.
I am including this although this has nothing to do with qmail or mh. But without a PPP line to your ISP there is no email at all. I had quite a bit of bother to get my ISDN working. The SusE distribution includes a configuration for ISDN, but I wanted something simpler. The stuff here was adapted from Bernhard Hailer's scripts. (Vielen, vielen dank!)
The following rc.config loads the necessary modules during initialisation:
#!/bin/bash # This is adapted Bernhard Hailer's old script LOCAL_NUMBER="91311234" # tel no. 091311234 REMOTE_NUMBER="0911123456" # ISP tel no. LOCAL_IP="192.168.0.99" # I have dynamic IP so this will do REMOTE_IP="188.8.131.52" # your ISP's gateway DEVICE="ippp0" SYSPATH="/sbin" ISDNCTRL="$SYSPATH/isdnctrl" case "$1" in start) # turn on isdn insmod /lib/modules/2.0.33/net/slhc.o insmod /lib/modules/2.0.33/misc/isdn.o sleep 1 # load the hisax module insmod /lib/modules/2.0.33/misc/hisax.o id=Tel0 type=5 protocol=2 irq=10 io=0x300 echo "starting isdn4linux" # global $ISDNCTRL verbose 0 $ISDNCTRL addif $DEVICE # create new interface $ISDNCTRL addphone $DEVICE in $REMOTE_NUMBER $ISDNCTRL addphone $DEVICE out $REMOTE_NUMBER $ISDNCTRL eaz $DEVICE $LOCAL_NUMBER $ISDNCTRL l2_prot $DEVICE hdlc $ISDNCTRL l3_prot $DEVICE trans $ISDNCTRL encap $DEVICE syncppp $ISDNCTRL huptimeout $DEVICE 300 $ISDNCTRL chargehup $DEVICE off $ISDNCTRL secure $DEVICE on $SYSPATH/ifconfig $DEVICE $LOCAL_IP pointopoint $REMOTE_IP metric 1 $SYSPATH/route add default $DEVICE $SYSPATH/ipppd /dev/ippp0 file /etc/ppp/options.ipppd & $SYSPATH/route del default ;; stop) #turn off isdn rmmod hisax.o sleep 1 rmmod isdn.o rmmod slhc.o echo "Shutting down isdn4linux" $ISDNCTRL delif ippp0 ;; *) echo "Usage: $0 (start|stop)" exit 1 ;; esac
I use the following script to dial out, it is called simply isdn on|off
The next lot is the ipppd options file /etc/ppp/options.ipppd
#!/bin/bash # This is based on an old script from Bernhard Hailer IP_ADDRESS="184.108.40.206" case "$1" in on) echo "Calling ippp0" /sbin/isdnctrl dial ippp0 # the sleep is important as it gives the PPP time to settle down echo "Sleep for 8s for PPP handshake" sleep 8s /sbin/route add default ippp0 echo "line open - checking...." # check whether PPP negotiation was successful: set `ping -qc3 -i1 $IP_ADDRESS 2>/dev/null | grep transmitted` if [ $4 -gt 0 ]; then echo "succeeded." echo "Starting fetchmail daemon" /usr/bin/fetchmail -d 600 -k -v -a -L /var/log/fetchmail echo "Flushing mail queue...." /usr/local/bin/serialmail/maildir2smtp ~alias/pppdir alias-ppp- mail.server.ip.no `hostname` else echo "failed!" /sbin/isdnctrl hangup ippp0 fi ;; off) echo -n "Shutting down fetchmail daemon" /usr/bin/fetchmail --quit /sbin/isdnctrl hangup ippp0 /sbin/route del default # and delete route echo "You're off line" ;; *) echo -e "\aUsage:" echo "isdn on" echo "isdn off" ;; esac

The net is so dynamic that it is pretty pointless to give sources. but for what it's worth:
The usual no guarantees, no money back, use at your own risk.
Has anyone got mh working with Maildir? I have not tried - the principle of not fixing a running system. If you have got it working please mail me your instruction for inclusion in the next revision
