<sub> Thinking how to debug
<sub> Can you telnet localhost 25?
<GhostRdr-> yeah
<sub> Try that
<sub> Is it fast?
<GhostRdr-> sr-71# telnet 0 25
<GhostRdr-> Trying 0.0.0.0...
<GhostRdr-> Connected to 0.
<GhostRdr-> Escape character is '^]'.
<GhostRdr-> 220 sr-71.defcon1.org ESMTP Sendmail 8.12.6p3/8.12.6; Tue, 16 Jan 2007 11:54:39 -0500 (EST)
<GhostRdr-> yeah
<sub> That was fast
<sub> telnet sr-71.defcon1.org 25
<GhostRdr-> same
<GhostRdr-> just as fast
<sub> It looks liek a networking issue
<GhostRdr-> this was a remote box
<GhostRdr-> %telnet sr-71.defcon1.org 25
<GhostRdr-> Trying 216.9.140.65...
<GhostRdr-> Connected to sr-71.defcon1.org.
<GhostRdr-> Escape character is '^]'.
<sub> Yes, I got that problem as well
<sub> Can I see the mc you used?
<GhostRdr-> sure
<GhostRdr-> sec
<GhostRdr-> http://www.defcon1.org/~ghostrdr/sr-71.defcon1.org.mc
<sub> FEATURE(`accept_unresolvable_domains')dnl ,- spam
<GhostRdr-> remove that?
<sub> disable that
<GhostRdr-> k
<sub> I don't see anything wrong in your config
<sub> This is freebsd 4?
<GhostRdr-> 4.7 Release
<sub> Did you update sendmail recently or make world?
<GhostRdr-> no
<GhostRdr-> thats the wierd part
<GhostRdr-> not did any upgrades since like oct.
<GhostRdr-> so, think its the sendmail?
<sub> No, I think it's the network
<GhostRdr-> as in ?
<sub> a networking issue
<GhostRdr-> ok
<GhostRdr-> dns ?
<sub> No, you tested dns a few minutes back
<GhostRdr-> or physical?
<sub> It would be network as in packet flowing from point A to point B
<GhostRdr-> ok
<GhostRdr-> but why would some mail work and the other not?
<sub> Because connectivity is different and some mail servers may be more tolerant about delays
<sub> I would ktrace the process just to make sure
<sub> ktruss
<GhostRdr-> ok
<GhostRdr-> whats that?
<GhostRdr-> like a traceroute?
<sub> man ktruss
<sub> No, like debugging processes
<GhostRdr-> k
<sub> BTW, disable that Local_check ruleset for now
<GhostRdr-> in the sendmail.cf?
<sub> Yes
<sub> for debugging network stuff, we would use tcpdump
<sub> anyone in here has ideas?
<sub> beb in a few minutes
<GhostRdr-> guess we are the only ones awake
<sub> brb
<GhostRdr-> ok
<sub> back
<sub> Okay, your issue was broken dnsbl
<sub> The problem is fixed now
<sub> You can watch your log and see it
<GhostRdr-> sure
<sub> Put back the dnsbls if you wish
<sub> You know the problem
<GhostRdr-> yeah
<GhostRdr-> thanks, I appreciate all of your help
<sub> You're welcome
<GhostRdr-> I need to get something to eat now my guts killing me
<sub> put back your antispam as you know what will happen without it
<sub> "You sent them an email to tell them their email is down? Good luck with that :-)"
<pip> heh
<sub> if I do "telnet [ipaddress] 25" I can connect to the server, is this okay? How do I disable it?
