HELP! Sendmail 8.12.9 problems up the wazzoo on FreeBSD 4.3....

I am sending / posting this message to

	FreeBSD questions mailing list
	comp.mail.sendmail newsgroup
	sendmail mailing list
	possibly other comp.unix.bsd.* newsgroups

I am quite stumped.  Any and all help is welcomed.  I will be working on this
problem all day.  Please feel free to contact me directly at 'steve at'
if you'd like to help me figure this puzzle out.

Sidenote:  I have downloaded/configure/compiled/installed Sendmail 8.12.9 
           successfully on a Solaris 8 box within the past few weeks.  Reading
	   all the fine documentation and working my way through that install
	   was painful enough as I found the learning curve pretty steep.  Now
	   I seem to have hit a brick wall doing the same thing on FreeBSD 4.3.
           Also... this seemed to be working just this past Tuesday (two days ago).
	   (Scratch that, it was working when I ran the FreeBSD 4.3 original 
	   sendmail 8.11.3 binary... which I have unfortunately overwritten.)
           You can find attached an e-mail I successfully sent myself by telnet'ing 
	   to port 25 from my own domain on that day at the end of this message,

Problem:   Freshly compiled Sendmail 8.12.9 is not working on a FreeBSD 4.3
	   system:  it does not accept local outbound mail, nor does it accept 
	   inbound mail.  Attempts to telnet to port 25 fail when the 
	   connection is closed instantaneously the moment one hits <return> 
	   after entering "data" on a line by itself.

	   More specifically, I am getting 

           "collect: premature EOM: Resource temporarily unavailable" 

	   "collect: I/O error on connection from localhost..." messages.

	   I have read the fine documentation and cannot figure this out.
	   I do not believe this to be the FAQ 3.10 problem, nor do I suspect
	   an MTU problem:  telnet, ftp, and ssh all work outbound, and I can
	   ssh inbound without problem.  I do not believe FAQ 3.12 or 3.20 apply
	   either.  In fact, just this past Tuesday (8-19-03), I was able to 
	   successfully telnet to port 25 from an outside domain and successfully 
	   sent myself a message.  I can't figure out what changes have been 
	   made that has broken sendmail so badly.

	   The above "collect:" messages occur whether I am sending mail, receiving
	   mail, whether I telnet to port 25 on the localhost or from outside
	   the domain, and whether I attempt to send mail using "Mail" or 
	   /usr/sbin/sendmail (e.g. /usr/sbin/sendmail -fsteve at 
	   steve at  The "errors" occur all the time, 100% of the

	   Recent changees ivolved tweaking some of the .mc files, but the 
	   resulting files (shown below) seem OK to me.  There is a mix of old 
	   and new files in /etc/mail.  Could this be a problem?  Could a mix 
	   of 8.12.9 binaries and older binaries still on the system (e.g. 
	   mail.local) be causing these kinds of problems?  But that doesn't 
	   make sense... because telnet'ing to port 25 always fails now.  

	   As this system is running FreeBSD 4.3, and I do not have the complete 
	   set of FreeBSD 4.3 CDROMs, and efforts to install the latest sendmail 
	   8.12.9 from packages fails (because apparently FBSD 4.3 is somehow incomp-
	   atible with the current packages), I downloaded the source from, and compiled it.  I also downloaded, compiled and
	   installed the following prior to building sendmail:

	   		m4 (GNU)
			OpenSSL 0.9.7b 10 Apr 2003
			Bind 9.2.2

	   A sample of the messages I am getting follows.  These messages
	   as shown in the following /var/log/maillog (FreeBSD 4.3) logfile:

NOTE:  The "collect: premature EOM: Resource temporarily unavailable" and 
       "collect: I/O error on connection from..." occur no matter whether I 
		telnet localhost 25      	(from the server itself)
		telnet 25      (from outside the domain)
		Mail steve at	(from outside the domain)
		Mail steve at		(from the server

       When telnet'ing to port 25... the errors occur immediately (instantaneously)
       after I hit the <return> key after having typed "data" on a line by itself.

    (1)  I *have* recently made some changes to hostnames in /etc/hosts and 
         /etc/rc.conf... Could some kind of a namespace collision / namespace
	 mismatch be causing the sudden demise of collect() ?

	 I have tried tweaking some /etc/hosts entries, and have modified the
	 external DNS server to match the name on the external interface, to
	 no effect.  That is:	xx.xx.xx.xx	(matches in /etc/hosts and DNS)        10.0.0.yy	(in /etc/hosts only)


		nameserver uu.uu.uu.uu

		NOTE:  "" is a different domain than my clients
			domain for which I use "" in this message.


		# $FreeBSD: src/etc/host.conf,v 1.6 1999/08/27 23:23:41 peter Exp $
		# First try the /etc/hosts file
		# Now try the nameserver next.
		# If you have YP/NIS configured, uncomment the next line
		# nis

    (2)  Has anyone compiled Sendmail 8.12.9 from scratch and been successful 
	 installing it on FreeBSD 4.x ?  Did you discover any gotchas?

    (3)  What other debugging commands can I run to try go get to the root of
         this problem short of running sendmail in gdb?  Or is that what it is
         going to take?   If so... can anyone point me to gdb crash-course
         (pun intended) ... it has been awhile:  in particular... can you 
         describe briefly how I would start sendmail in the debugger and have
         it run normally otherwise?  Can someone refresh my tired memory on
         how I would set a breakpoint in the collect() routine?

         Is it this easy:

	     sudo gdb /usr/sbin/sendmail -bD -q15m

	 or should I try:

	     sudo gdb /usr/sbin/sendmail -bD -qf


    (4)   Could a mismatch of original FreeBSD 4.3 binaries / new Sendmail 8.12.9
          freshly compiled binaries be interacting in some unforeseen way to 
	  cause these problems?  
	  I am guessing no... because I get the collect: errors ALL the time, 
	  even when I start sendmail binary by hand ( e.g. sudo /usr/sbin/
	  sendmail -bd -q15m) and then telnet to port 25...

	NOTE:  NEVERMIND... this was sendmail 8.11.3... so it was working with
               the /etc/mail/* files *before* I put the 8.12.9 binary in place.
               Unfortunately... I overwrote the original FreeBSD 4.3
               /usr/sbin/sendmail binary.

Sorry this is so long.  I've endeavoured to be as complete and thorough as possible.
