        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 '[EMAIL PROTECTED]'
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 [EMAIL PROTECTED] 
           [EMAIL PROTECTED]).  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
           sendmail.org, 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:

Aug 21 06:17:26 city sendmail[1965]: h7LCHQvI001965: from=steve, size=41,    \

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 city.example.com 25      (from outside the domain)
                Mail [EMAIL PROTECTED]  (from outside the domain)
                Mail [EMAIL PROTECTED]          (from the server city.example.com

       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:

                city-gw.example.com     xx.xx.xx.xx     (matches in /etc/hosts and DNS)
                city.example.com        10.0.0.yy       (in /etc/hosts only)


                search some.server.clients_isp.net
                nameserver uu.uu.uu.uu
                nameserver tt.tt.tt.tt  

                NOTE:  "clients_isp.net" is a different domain than my clients
                        domain for which I use "example.com" 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...

      Test to '[EMAIL PROTECTED]' 
      From    [EMAIL PROTECTED]

      Telnet 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.
Please feel free to contact me at '[EMAIL PROTECTED]' with any questions, suggestions
