Sendmail problem

AL_3001 — Thu, 17 Apr 2008 09:39:19 GMT

Hi Friends,
There was a filed disk on one of the SMTP server with IP address 150.150.119.87 is /etc/hosts. We were asked to change it to 150.150.101.103 to route all the mails through this server. We made the nexessary changes in /etc/hosts file but the e-mails are not going through for BW team. As per the mail logs from /var/adm/syslog/mail.log:
---------------------------------------
Apr 17 11:29:56 ukcsbpw1 sendmail[26950]: AAA10577: to=pcmcpnl@[161.89.58.5], ctladdr=root (0/3), delay=11:24:55, xdelay
=00:01:16, mailer=esmtp, relay=[161.89.58.5] [161.89.58.5], stat=Deferred: Connection timed out with [161.89.58.5]
---------------------------------------

Kindly assist and let me know what o/p you'll require because i want a solution for this ASAP as it is not working for past many days.

Thank You all in advance.

Regards,
Ashish

Hi,
your smtp server IP address was 150.150.119.87 and then you changed it to 150.150.101.103.
Did you change your MX entry in your DNS?
Check that your MX entry is updated or not.
your IP block 161.89.58.5, this block is RELAY to your access file?

Thanks & Regards

have you tried
sendmail -bv email@address.com

This may give you more info.

Also are any other servers using the SMTP server successfully?

Whose system is 161.89.58.5? I can't talk
to it either:

alp $ telnet /port = 25 161.89.58.5
%TELNET-I-TRYING, Trying ... 161.89.58.5
%TELNET-E-CONNFAIL, Failed to connect to remote host
-SYSTEM-F-TIMEOUT, device timeout

150.150.x.x looks like Korea, and 161.89.58.5
looks like the Netherlands. I'd guess that
the problem is in Europe, not Asia. That is,
unless you didn't think that you were trying
to send the e-mail to Europe. I see that
161.89.58.5 is not likely to be a real mail
host:

ALP $ nslookup 161.89.58.5
Server: alp-l.antinode.org
Address: 10.0.0.9

*** alp-l.antinode.org can't find 161.89.58.5: Non-existent host/domain

Where are you trying to send this e-mail?

Shalom Ashish,

stat=Deferred: Connection timed out with [161.89.58.5]

That system is not accepting your mail.

Could be for any number of reasons, most of which fall into anti-spam configuration.

Possibilities:
1) Lack of publically resolvable domain name.
2) No reverse lookup address.
3) Mismatch between domain name in sendmail and the domain name of the ip address on the public internet.
4) They also simply could have denied you.

I'd check out http://www.sendmail.org and learn the basics of setting up a sendmail server.

You also might find a properly configured relay server smtp relay server in your LAN.
