Hi, 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 '[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, however. 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 time. 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. Grrrr.... 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 BerkeleyDB.4.1 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: h7LCHQvI001965: from=steve, size=41, \ class=0, nrcpts=1, msgid=<[EMAIL PROTECTED]>\ , [EMAIL PROTECTED] Aug 21 06:17:26 city sendmail: h7LCHQJF001966: collect: premature EOM: \ Resource temporarily unavailable Aug 21 06:17:26 city sendmail: h7LCHQJF001966: SYSERR(root): collect: \ I/O error on connection from localhost, from=<[EMAIL PROTECTED]> Aug 21 06:17:26 city sendmail: h7LCHQJF001966: \ from=<[EMAIL PROTECTED]>, size=0, class=0, nrcpts=1, proto=ESMTP, \ daemon=MTA, relay=localhost [127.0.0.1] Aug 21 06:17:26 city sendmail: h7LCHQvI001965: [EMAIL PROTECTED], \ ctladdr=steve (1024/20), delay=00:00:00, xdelay=00:00:00, mailer=relay, \ pri=30034, relay=[127.0.0.1] [127.0.0.1], dsn=4.0.0, stat=Deferred: Connection \ reset by [127.0.0.1] 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 itself) 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. Question(s): (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) /etc/resolv.conf: 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. /etc/host.conf: # $FreeBSD: src/etc/host.conf,v 1.6 1999/08/27 23:23:41 peter Exp $ # First try the /etc/hosts file hosts # Now try the nameserver next. bind # 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...
