qpsmtpd-forkserver on Mac OS X

[Michael Glaesemann <grzm@seespotcode.net>]

Hello!

I'm trying to get qpsmtpd-forkserver[1] to start automatically on  
server restart.

Mac OS X 10.4.6 (Intel Mac Mini)
runit-1.5.1
qpsmtpd-0.32 -- An easily extensible smtp server written in Perl.

 From what I can tell, the qpsmtpd installation is working fine, and  
the runit installation is okay. However, using the two together  
doesn't seem to work. Details of my configuration are below. I've  
googled and looked through the documentation on using runit with  
qpsmtpd [2] and runit with launchd [3], but am at a loss as to what I  
have misconfigured.

I've posted this to the runit mailing list first, as it appears that  
my qpstmpd installation is okay. If it looks like it's a qpstmpd  
configuration problem, I'll definitely ask there as well.

Any hints or suggestions on what else I might check in my  
configuration, or where I might find additional information is  
appreciated. If there's any information about the setup I can provide  
to make it easier to diagnose, please let me know.

Thanks!

I can run the qpstmpd-forkserver from the command line using

sudo /usr/local/qpsmtpd/qpsmtpd-forkserver --detach --user www --port 25

After launching the qpsmtpd-forkserver from the command line, I can  
connect to the smtp server via telnet:

$ telnet localhost 25
Trying ::1...
telnet: connect to address ::1: Connection refused
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
220 wilde.local ESMTP qpsmtpd 0.32 ready; send us your mail, but not  
your spam.

The server also delivers mail as expected when launched from the  
command line.

The qpsmtpd wiki gives instructions[2] on how to configure qpsmtpd- 
forkserver with runit. Here's /var/service/qpsmtpd/run

$ cat /var/service/qpsmtpd/run
#!/bin/bash
unset PERL_UNICODE
/usr/local/qpsmtpd/qpsmtpd-forkserver --detach --user www --port 25
$

I've installed runit according to the instructions, including the  
modifications for installation on Mac OS X (modifications to src/conf- 
ld and src/Makefile)

  Installation appeared to go fine. I saw no errors at the end of the  
installation script.

$ ls -la /sbin/runsvdir-start
-rwxr-x---   1 root  wheel  554 Jun  5 11:17 /sbin/runsvdir-start

$ ls -la /var/service/qpsmtpd/
total 8
drwxr-xr-x   5 root      wheel  170 Jun  5 17:19 .
drwxr-xr-x   3 root      wheel  102 Jun  5 11:24 ..
drwxr-xr-x   3 root      wheel  102 Jun  5 17:20 log
-rwxr-xr-x   1 saiadmin  wheel   99 Jun  5 13:08 run
drwx------   8 root      wheel  272 Jun  5 17:52 supervise

/var/service/qpsmtpd/supervise was created automatically and I can  
see that the modification time is incrementing. This is why I think  
runit is properly installed.

$ cat /var/service/qpsmtpd/run
#!/bin/bash
unset PERL_UNICODE
/usr/local/qpsmtpd/qpsmtpd-forkserver --detach --user www --port 25

When org.smarden.runit.plist is loaded (either manually using  
launchctl or automatically on server restart), qsmtpd-forkserver  
doesn't appear to work. However, something is definitely running on  
port 25:

$ netstat -atn | grep -e '\.25'
tcp4       0      0  *.25                   *.*                     
LISTEN
$

Connecting via telnet fails:
$ telnet localhost 25
Trying ::1...
telnet: connect to address ::1: Connection refused
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
Connection closed by foreign host.
$

I don't see anything in /var/log/system.log (where launchd problems  
are logged) or /var/log/mail.log (the qpsmtpd log). When using  
launchd/runit, nothing is logged to /var/log/mail.log at all. (When  
run from the command line, mail.log contains information about  
connections to the smtp server.)
