qmail effectively cannot deliver messages to mailman due to mailman rejecting the delivery based on group ID. Reproducible: Always Steps to Reproduce: 1.emerge qmail 2.emerge mailman 3.hack qmail's control/virtualdomains to include the appropriate list.xxx.xxx domain and ship messages to it at qmail 4.set up a list (using ~mailman/bin/newlist) 5.set up qmail aliases 6.attempt to mail to the list Actual Results: @40000000417c2cbf1029812c status: local 0/10 remote 0/20 @40000000417c2d12044d43d4 new msg 88296528 @40000000417c2d12044e64e4 info msg 88296528: bytes 454 from <relsqui@boogeyman.a rmory.com> qp 14062 uid 1063 @40000000417c2d12090a27d4 starting delivery 628: msg 88296528 to local treasureh unt@treasurehunt.mine.nu @40000000417c2d12090a991c status: local 1/10 remote 0/20 @40000000417c2d120a27b564 delivery 628: deferral: Group_mismatch_error.__Mailman _expected_the_mail/wrapper_script_to_be_executed_as_group_"mailman",_but/the_sys tem's_mail_server_executed_the_mail_script_as/group_"nofiles".__Try_tweaking_the _mail_server_to_run_the/script_as_group_"mailman",_or_re-run_configure,_/providi ng_the_command_line_option_`--with-mail-gid=nofiles'./ @40000000417c2d120a28c6d4 status: local 0/10 remote 0/20 Expected Results: It should deliver seamlessly and mailman should farm it out to the correct list. It can supposedly be fixed by setting the MAILGID line in the mailman ebuild from the GID of mailman (280 on my box) to the GID of nofiles (200 on my box), although I'm still having problems after a re-emerge. # cat /var/qmail/alias/.qmail-mailman |preline /var/lib/mailman/mail/wrapper post mailman # ls -l /var/qmail/bin/preline -rwxr-xr-x 1 root qmail 20584 Aug 11 05:03 /var/qmail/bin/preline # ls -l /var/lib/mailman/mail/wrapper -rwxr-sr-x 1 mailman mailman 7260 Oct 19 04:54 /var/lib/mailman/mail/wrapper # emerge info emerge info Portage 2.0.51 (default-x86-2004.0, gcc-3.3.4, glibc-2.3.3.20040420-r2, 2.6.8.1 i686) ================================================================= System uname: 2.6.8.1 i686 Pentium III (Katmai) Gentoo Base System version 1.4.16 distcc 2.16 i686-pc-linux-gnu (protocols 1 and 2) (default port 3632) [disabled] Autoconf: sys-devel/autoconf-2.59-r5 Automake: sys-devel/automake-1.8.5-r1 Binutils: sys-devel/binutils-2.14.90.0.8-r1 Headers: sys-kernel/linux26-headers-2.6.8.1 Libtools: sys-devel/libtool-1.5.2-r5 ACCEPT_KEYWORDS="x86" AUTOCLEAN="yes" CFLAGS="-O3 -march=pentium3 -fomit-frame-pointer" CHOST="i686-pc-linux-gnu" COMPILER="" CONFIG_PROTECT="/etc /etc/tomcat4 /usr/X11R6/lib/X11/xkb /usr/kde/2/share/config /usr/kde/3.2/share/config /usr/kde/3/share/config /usr/share/config /var/qmail/ alias /var/qmail/control" CONFIG_PROTECT_MASK="/etc/gconf /etc/terminfo /etc/env.d" CXXFLAGS="-O3 -march=pentium3 -fomit-frame-pointer" DISTDIR="/usr/portage/distfiles" FEATURES="autoaddcvs autoclean buildpkg ccache collision-protect distlocks sandbox userpriv usersandbox" GENTOO_MIRRORS="http://gentoo.osuosl.org http://distro.ibiblio.org/pub/Linux/distributions/gentoo" MAKEOPTS="-j8" PKGDIR="/usr/portage/packages" PORTAGE_TMPDIR="/var/tmp" PORTDIR="/usr/portage" PORTDIR_OVERLAY="" SYNC="rsync://rsync.gentoo.org/gentoo-portage" USE="X509 aalib accessibility acl acpi acpi4linux afs aim alsa amd apache2 apm arts artswrappersuid asterisk async avi berkdb bidi bitmap-fonts bzlib cap cdr cdrom chroot clanJavaScript crypt cscope cups curl curlwrappers devfs devfs26 devmap dio directfb distcache divx4linux djbfft encode erandom esd ethereal f77 fam fbcon flash fltk foomaticdb freetts fs ftp gcj gcl gdbm gif gimp gimpprint glut gphoto2 gpm gtk2 hbci icc icc-pgo icq ifc imagemagick imap imlib inetd ipv6 ipv6arpa java javacomm javadoc javamail javascript jikes jit jp2 jpeg kerberos krb4 libg++ libwww lids live log4j lzw mad maildir makecheck memlimit mhash mikmod ming mmap mmx mng motif mozilla mpeg mpeg4 mpi mplayer msn music mysql mysqli nagios-dns nagios-ntp nagios-ping nagios-ssh nas ncurses net nethack nis nls nodroproot nptl ntlm ocaml odbc oggvorbis oldworld openal opengl oscar oss pam pcntl pcre pdflib perl php physfs pic pie png pnp posix prelude python quicktime readline ruby samba sasl scanner sdl slang sockets sox spell spl src sse ssl svga sysvipc tcltk tcpd threads tiff truetype usagi usb x86 xchatnogtk xchattext xfs xml2 xmms xprint xv yahoo zlib"
