no, really

no, really, the comma shouldn't be there. (or the title should be "what it is, and what we are doing here" without the question mark). I used to be a spelling and grammar nazi in a past life.

bad comma

You're going to have to back that up with an external link to a well-accepted style guide that clearly states that using a comma there is wrong, and even then I don't promise to care. =) --Jimbo 20:36, 15 Dec 2004 (EST)

grammar nazi bs

http://cctc2.commnet.edu/grammar/commas.htm

while not incorrect to use the comma there, it makes for bad scanning.

full path

I'm not well up on wiki etiquette so I just thought I'd add a comment here on a small change I made.

I added two /etc/ to the following section to ensure the command will work correctly when executed outside of the /etc directory

ph34r# rehash
ph34r# cat /etc/tcp.smtp | tcprules /etc/tcp.smtp.cdb /etc/tcp.smtp.tmp

Also for some reason I couldn't get make enable-qmail to execute. It was probably something I was doing wrong but should anyone run into similar difficulty just check out the file work/qmail-enable inside the qmail+smtp_auth+tls ports directory.

Its easy enough to read what it does and then execute the commands for disabling sendmail and enabling qmail manually.

P.S. Great guide, it was very helpful, Eoin

that's odd

Huh - that's odd (that make qmail-enable ran into problems). Never seen that before. And your change was good, thanks. =) --Jimbo 10:59, 7 Jun 2005 (EDT)


oddly enough

so for giggles, i'm installing a listserv (using mailman...i'll let you know how ti works out) and I'm using FreeBSD for the hell of it. and I am also having problems doing a make enable-qmail. going into the work dir doesn't shed any light on the matter as the only thing in there is:

# ls -la
total 28
drwxr-xr-x  3 root  wheel    512 Jul 13 16:18 .
drwxr-xr-x  3 root  wheel    512 Jul 13 16:18 ..

-rw-r--r--  1 root  wheel      0 Jul 13 16:18 .patch_done.qmail-smtp_auth+tls-1.03.20020519_1._var_qmail
-rw-r--r--  1 root  wheel    311 Jul 13 16:18 SMTP_AUTH+TLS.readme

drwxr-xr-x  2 root  wheel  16896 Jul 13 16:18 qmail-1.03

so what does enable-qmail do (as a target to make) that just a make install doesn't?



See the directory that I bolded in your ls output there? That's where the goodies are. That's how the work directory from a built port always looks. But in this case, what you actually want to look at is files/enable-qmail.in. What it does is, so far as I can tell, is just make sure that the mail command gets realiased to qmail from whatever it was aliased to before, by the means of copying a conf file. From looking at the Makefile, though, it looks as though the qmail-enable target may not even exist anymore; it looks like an installation of qmail since 1.03_3 will probably make a /var/qmail/scripts directory instead, from which you can run the script /var/qmail/scripts/enable-qmail. Lemme know what you find out, okay? --Jimbo 00:00, 14 Jul 2005 (EDT)



It might be worth mentioning that if vpopmail is ever upgraded then you need to manually reset the file attributes of /usr/local/vpopmail/bin/vchkpw or users will have login troubles.

Great Guide but I am having problems with SqWebmail Portion, it seems now that the in the ports tree when you install sqwebmail you get courier-authdaemond installed instead of sqwebmail-authdaemond, and I can not find anywhere the PREFIX script I need to replace in the .sh files, and I notice that courier-authdaemond has PREFIX already set to /usr/local already.......so I thought I was good to go.

but after I start the daemons and point my browser to Sqwebmail I get a 500 error with: The webmail system is temporarily unavailable. An error occured in function write: Socket is not connected?

I notice that in the courier-authdaemond.sh there is a setting for socket with the base directory being $authbase/run/socket however there is not a socket file or folder in /var/run

Any Thoughts?

are you sure that $authbase == /var/run? I'd do a "find / | grep socket" to see where it might be..

maybe something else is holding the socket open? I'm guessing you've got sqwebmail tied into apache -- is your apache config ok? I don't run webmail myself so I probably won't be much help.

--Dave 09:47, 15 Sep 2005 (EDT)

have you tried to ps waux | grep authdaemon?

Try to start the authdaemon - /usr/local/etc/rc.d/(whatever)daemond.sh start - and then ps waux | grep authdaemon. Is it running?

If it isn't, you're going to need to figure out why. Usually the easiest way to deal with that PREFIX crap is just to snip it out and sub in the /usr/local/ hard-coded. --Jimbo 02:07, 16 Sep 2005 (EDT)

lsof to find open sockets maybe

might want to use lsof to see what's holding the socket open too...

--Dave 11:56, 17 Sep 2005 (EDT)

this article should be updated...

...unfortunately, until i reinstall freebsd on a sparc at work, i have no bsd to do it with; the make qmail-enable thing doesn't work (i do the qmailrocks.org install myself....although i've been playing with postfix recently, and i'm going to install zimbra on my new listserver (why i moved my x86-64 box to CentOS instead of FreeBSD)....

Checking Environment Variables

Note to self: checking the environment variable TCPREMOTEINFO is a better way to check for authenticated SMTP, but qsheff doesn't pass that along - you'd need to wrap BEFORE qsheff, not after, in order to pick up on that. Which is beginning to beg the point of using qsheff at all... here is a complete list of environment variables present when qmail-queue is run:

TCPLOCALPORT=2525
USER=yourmom
SSH_CLIENT='24.168.100.50 3295 22'
MACHTYPE=i386
MAIL=/var/mail/mom
TCPREMOTEIP=70.150.138.10
VENDOR=intel
SHLVL=2
HOME=/root
PROTO=TCP
SSH_TTY=/dev/ttyp0
PAGER=more
PS1='$ '
OPTIND=1
PS2='> '
GROUP=wheel
LOGNAME=mom
TERM=xterm
BLOCKSIZE=K
TCPREMOTEPORT=1935
PPID=92605
PATH=/sbin:/bin:/usr/sbin:/usr/bin:/usr/games:/usr/local/sbin:/usr/local/bin:/usr/X11R6/bin:/root/bin
REMOTEHOST=24.168.100.50
TCPLOCALIP=66.154.114.98
SHELL=/bin/csh
HOST=blackbox.tehinterweb.net
IFS='
'
OSTYPE=FreeBSD
TCPLOCALHOST=mail.jrssystems.net
PWD=/home/mom
TCPREMOTEINFO=jim@jrssystems.net
SSH_CONNECTION='24.168.100.50 3295 66.154.114.98 22'
FTP_PASSIVE_MODE=YES
HOSTTYPE=FreeBSD
EDITOR=vi

No black magic. So - ditch qsheff entirely and simply wrap qmail-queue itself?

ENVs to particularly note: TCPREMOTEINFO, TCPREMOTEIP

Final note for the night: don't see why not do my own standalone wrapper; mail got delivered fine while I was piping environment variables to a text file and piping STDIN to qmail-queue just now. No black magic a'tall, I don't know why wrapping qmail-queue wasn't seeming to work for me the last time I tried it; maybe I just didn't have the permissions set so that my wrapper would execute then?

AHA there is one bit of magic: qmail-queue actually READS its STDOUT to get addressing information normally; that's how bcc works. Example:

open (FH, "<&=1");
  @so = <FH>;
close (FH);

in a wrapper will get you the following in @so, from a message bcc'ed to yourmom@momscrib.com:

Fdad@pimpshack.netTyourmom@momscrib.com

Harrrr....

--Jimbo 02:58, 21 Feb 2006 (EST)

Okay FOR REAL final line for the night: turns out that trying to get Perl to write to a child's STDOUT is beyond fucking painful. However it looks like /usr/ports/mail/qmail-qfilter will do the job nicely, it can be compiled as a plain (brown) wrapper with a minor alteration to the source code and takes a "get out of here you jackass" exit code (31) or a silent drop exit code (99) so there's good range of functionality.

it runs like this: put a shell script in place of qmail-queue like so:

#!/bin/sh
exec /path/to/qmail-qfilter \
       /path/to/spamc -- \
       /path/to/reject-message-with-spamrating-over-5 -- \
       /path/to/reject-message-with-unwantedkeyword -- \
       /path/to/reject-message-with-sobig

Sheesh. It's 5AM again. =( --Jimbo 05:00, 21 Feb 2006 (EST)

Confirmed. qmail-qfilter works fine. Just need to rework maildump.pl to dump the message to STDOUT instead of trying to feed it to qmail-queue directly by itself. --Jimbo 05:15, 21 Feb 2006 (EST)

SETUID perl?

probably will need to compile a new version of Perl from ports with MAKE -DENABLESUIDPERL=yes so's we can run the scanner as vpopmail / vchkpw, if you want to run the script setuid (as vpopmail, so it can deliver mail to normal MTA-accessible maildirs). It's better and easier to use sudo, IF you have the option - but if sudo craps out on you and starts acting buggy (it has happened to me on some servers but not others), running setuid IS a workable fallback option.

qqxrc.patch

save this (gotten from http://www.wijata.com/software/#QMAIL) as /home/[yourname]/qqxrc.patch

cd /usr/ports/mail/qmail-tls make config : make sure to select the SMTP_AUTH knob and the RCDLINK knob; optionally you may choose to select the local-time knob also - DON'T select the double-bounce knob unless you want to patch by hand, the automated patch will FAIL if you do. make fetch make patch cd work/qmail-1.0.3 patch < /home/[yourname]/qqxrc.patch cd ../.. make install

Media:Qqxrc.patch.txt

now you can make install as normal

to use it, create /var/qmail/control/qqxrcode and populate it like so:

32 Message permanently rejected (Virus detected)
33 Message permanently rejected (Spam detected)

Net result: exiting from a filter program with a 32 or 33 gets you the above messages.

Normal SMTP 554 is from an exit 31, so I'd recommend sticking stuff in between 32 and 40.

qmail-queue replacement

this is the new qmail-queue:

#!/bin/sh
exec /usr/local/bin/qmail-qfilter \
        /usr/local/bin/sudo -u vpopmail /usr/local/bin/smartscan.pl

note be sure to set up sudoers properly and to make sure clamd and spamd are running as vpopmail (or you may want clamd to run as root), and chown vpopmail /usr/local/vpopmail/smartscan/tmp && chmod 700 /usr/local/vpopmail/smartscan/tmp to finish up. (Trying to be paranoid about permissions in the working directory to avoid possible race conditions potentially allowing unpriv users to do nasty things to email on its way in.)

run setuid, or use sudo?

You can do either one, but if you're forced to run in a setuid environment - INCLUDING if smartscan is called by a setuid script - you may have issues with sudo randomly acting like it isn't set up right, and "Password:" "Password:" "Password:" littering any root console you open and nasty messages all through your log files... in spite of things actually getting DELIVERED properly. Not sure why; my guess is that there's a race condition and occasionally Perl uses a real instead of an effective uid when it runs sudo, if it's running setuid itself? Regardless, if you don't HAVE to run the script setuid, it's a lot easier simply to specify sudo in your $delivery_agent variable... but if you DO have to, the script will run fine under taint checks.

BETTER OPTION: run smartscan itself sudo to vpopmail from the qmail-qfilter invocation. In sudoers, make sure you set

ALL ALL=(vpopmail) NOPASSWD: /usr/local/vpopmail/smartscan/smartscan.pl

because the UID qfilter is running under will change depending on whether it's called from a local injection process or an incoming mail from a remote host. Make sure clamd runs either as vpopmail or as root, and make sure spamd runs as vpopmail, and from there you're fine.

qmail-ldap

well, it's awkward because i didn't think it would work to have the mail toaster article do the qmail-ldap thing -- a lot of folks aren't going to have AD or LDAP, and a mail-toaster article that doesn't have ldap stuff in it is going to be lots more useful than one that does, but i have yet to find a single article that talks about installing qmail-ldap and getting it to talk to MS's AD and slapping a gui on it for management. which I'm going to do for my particular setup. except I haven't done that before so the article I'm going to make but haven't yet is basically going to be my scratch-pad until I get it right :)

in looking over the discussion page, i'm thinking a lot of these notes deserve their own articles, not to be buried in some other article's talk page...maybe a generalized "qmail notes and tips" page?

the notes on this page

Are actually towards redoing the "real article" in a very big way; all of this stuff was my scratch paper while I built the 2.0 version of the toaster for a client. They need organization and rewriting "as a real article" and migration to "the real article." I never intended that they just live here forever, I just didn't want to bung up the actual article while I hacked together the new system. =)

As far as the qmail-ldap goes - why don't you just make a stub, and work from there? --Jimbo 22:09, 19 April 2006 (EDT)

yeah, that's why the link's there....

so i can find the article i'm going to write when i get around to it :)

CRAM-MD5 isn't really supported... *patch*

Qmail will report that it supports CRAM-MD5 authentication when EHLO'ed by an incoming SMTP connection, but it's a lie - Qmail's native auth module might support it, but authvchkpw doesn't. At best, this means that incoming clients will pause for about 3 seconds while they fail out on CRAM-MD5 authentication before they fall back on LOGIN or PLAIN (either of which work fine). At worst (so far, I've only seen this with the Pegasus mail client), they'll just bomb out completely and refuse to send mail.

After issuing a make patch, cd'ing to work/qmail-1.03, and patching with media:Qqxrc.patch.txt, patch with media:Qmail-noCRAM-MD5.patch.txt to fix the issue and make authentication smooth, fast, and reliable.

ph34r# cd /usr/ports/mail/qmail
ph34r# make patch
ph34r# cd work/qmail-1.03
ph34r# patch < /home/username/qqxrc.patch
ph34r# patch < /home/username/qmail-noCRAM-MD5.patch

Now you can proceed with the actual building and installation of the port.
