This could be caused by a firewall, which cuts off ICMP traffic. This is rather common these days, even if it is bad firewalling style to do so.
I'm not ruling that out either... but as ya know I have to rule other options out first in this situation. And that means doing some stalking on that mail and finding out where the bread crumb trail finishes. Just not sure how to go about doing this form of tracking.

I checked the MX record and it showed the mail servers as some amateurish outfit, when I looked at their website - but I'm not one to judge a book by its cover :-)
How would I confirm that the mail exchanger is working? Is that where I telnet into it?

I looked for a log file, but didn't manage to find it at the time. I will check that directory location tomorrow, but if it isn't there is there a way to create one temporarily for sendmail?
Hi Friends,
Can any of you explain me about the below line of code?

Im not able to understand, what exactly it is doing :confused:
Any help would be useful for me.

etrn
etrn(1M) System Administration Commands etrn(1M)NAME
etrn - start mail queue run
SYNOPSIS
etrn [-b] [-v] server-host [client-hosts]
DESCRIPTION
SMTP's ETRN command allows an SMTP client and server to interact, giving the server an opportunity to start the processing of its queues
for messages to go to a given host. This is meant to be used in start-up conditions, as well as for mail nodes that have transient connec-
tions to their service providers.
The etrn utility initiates an SMTP session with the host server-host and sends one or more ETRN commands as follows: If no client-hosts are
specified, etrn looks up every host name for which sendmail(1M) accepts email and, for each name, sends an ETRN command with that name as
the argument. If any client-hosts are specified, etrn uses each of these as arguments for successive ETRN commands.
OPTIONS
The following options are supported:
-b System boot special case. Make sure localhost is accepting SMTP connections before initiating the SMTP session with server-
host.
This option is useful because it prevents race conditions between sendmail(1M) accepting connections and server-host
attempting to deliver queued mail. This check is performed automatically if no client-hosts are specified.
-v The normal mode of operation for etrn is to do all of its work silently. The -v option makes it verbose, which causes etrn
to display its conversations with the remote SMTP server.
ENVIRONMENT VARIABLES
No environment variables are used. However, at system start-up, svc:/network/smtp:sendmail reads /etc/default/sendmail. In this file, if
the variable ETRN_HOSTS is set, svc:/network/smtp:sendmail parses this variable and invokes etrn appropriately. ETRN_HOSTS should be of the
form:
"s1:c1.1,c1.2 s2:c2.1 s3:c3.1,c3.2,c3.3"
That is, white-space separated groups of server:client where client can be one or more comma-separated names. The :client part is optional.
server is the name of the server to prod; a mail queue run is requested for each client name. This is comparable to running:
/usr/lib/sendmail -qR client
on the host server.
EXAMPLES
Example 1: Using etrn
Inserting the line:
ETRN_HOSTS="s1.domain.com:clnt.domain.com s2.domain.com:clnt.domain.com"
in /etc/default/sendmail results in svc:/network/smtp:sendmail invoking etrn such that ETRN commands are sent to both s1.domain.com and
s2.domain.com, with both having clnt.domain.com as the ETRN argument.
The line:
ETRN_HOSTS="server.domain.com:client1.domain.com,client2.domain.com"
results in two ETRN commands being sent to server.domain.com, one with the argument client1.domain.com, the other with the argument
client2.domain.com.
The line:
ETRN_HOSTS="server1.domain.com server2.domain.com"
results in set of a ETRN commands being sent to both server1.domain.com and server2.domain.com; each set contains one ETRN command for each
host name for which sendmail(1M) accepts email, with that host name as the argument.
