Sending mail to freebsd-questions

2003-03-17 Thread Paul D . Lathrop 
I was attempting to send a different question to this list, when I ran 
smack dab into a more pressing problem. When I sent the mail, it never 
reached the list. Further investigation found this message in my mail 
logs:

Mar 16 22:10:32 rackspace postfix/smtp[28417]: 8B00131673: 
to=[EMAIL PROTECTED], relay=mx1.freebsd.org[216.136.204.125], 
delay=11, status=deferred (host mx1.freebsd.org[216.136.204.125] said: 
450 Client host rejected: cannot find your hostname, [65.61.155.146] 
(in reply to RCPT TO command))

What exactly does this mean, and how can I fix it? I don't want my mail 
server to be crippled in this manner.

Thanks,
Paul D. Lathrop (usually [EMAIL PROTECTED])

I would think that it is a temporary glitch. freebsd.org requires that
your IP address has forward and reverse DNS setup. I've check and it does
seem to be ok now

[EMAIL PROTECTED]:~$ host  rackspace.mqtweb.com
rackspace.mqtweb.com is an alias for mqtweb.com.
mqtweb.com has address 65.61.155.146
[EMAIL PROTECTED]:~$ host 65.61.155.146
146.155.61.65.in-addr.arpa domain name pointer rackspace.mqtweb.com.

The IP address of your server resolves fine now.  It was probably just
a temporary DNS outage.

 What exactly does this mean, and how can I fix it? I don't want my
 mail server to be crippled in this manner.

The FreeBSD.org mail server, in an effort to stop some spammers,
requires that hosts mailing through it have both a forward and reverse
DNS lookup that works (host - ip address and address - host).

When your message was received, it failed to resolve your IP address
[65.61.155.146] properly, and rejected the post.

Now it should work fine.  hub.freebsd.org below is the primary MX for
the FreeBSD.org domain:

: [EMAIL PROTECTED]:10]/home/keramida$ hostname
: hub.freebsd.org
:
: [EMAIL PROTECTED]:09]/home/keramida$ host 65.61.155.146
: 146.155.61.65.IN-ADDR.ARPA domain name pointer rackspace.mqtweb.com
:
: [EMAIL PROTECTED]:10]/home/keramida$ host rackspace.mqtweb.com
: rackspace.mqtweb.com is a nickname for mqtweb.com
: mqtweb.com has address 65.61.155.146
: mqtweb.com mail is handled (pri=10) by mail.mqtweb.com
