when telneting to sendmail I get...

[David McDowell]

When I telnet to sendmail on port 25, my response is as follows: 220 localhost.localdomain ESMTP Sendmail 8.11.6/8.11.6; Tue, 21 Jan 2003 10:49:1
6 -0500

I cannot figure out why I continue to get localhost.localdomain instead of host.domain.com. I also get localhost.localdomain as the HELO in my email headers. Any ideas? I've racked my brain on this one. I have DNS setup for this domain and an MX record. Sending and recieving of emails works perfectly between this sendmail and an exchange server which is in another domain, both internal to my network.
Thanks in advance!!

in /etc/mail/sendmail.cf

Change

# #Dj$w.Foo.COM #
# to #
# Dj$w.hp.com #
#

where hp.com is your actual domain name.

or DJhp.com

If $w is being set as localhost

The real solution is to change you hostname to fully qualified domainname.

/etc/rc.config.d/netconf

change hostname to hostname.hp.com

Where hp.com is your genuine domain name.

Good Luck.

I have been taught not to edit sendmail.cf directly, that it is best to edit sendmail.mc and use m4 to apply changes to the .cf file. Do you know how I can avoid editing the .cf directly? Thanks.

OK, setting hostname to FQDN actually solved that part of the issue! When I telnet to port 25, I now get: 220 host.domain.com ESMTP Sendmail 8.11.6/8.11.6; Tue, 21 Jan 2003 11:31:
24 -0500
Thanks!

Now to continue that, in my latest email header, when using PINE on the local server, I get this:

Microsoft Mail Internet Headers Version 2.0

Specifically my question is the line:
Received: from localhost (user@localhost)

Is this a PINE configuration or am I still missing something in my sendmail config?

Thanks! Making great progress with this forum, wish I would have joined sooner!

The "Received: from localhost" header is normal for an MUA (mail user agent, e.g. PINE) running on the same machine as the MTA (mail transport agent, e.g. sendmail). The MUA connects to the MTA via the 127.0.0.1 psuedo-interface, and the headers are written accordingly. On most DNS servers, there's an inverse arpa zone set up for network 127.0.0 in /etc/named.boot:
directory /etc/named.data ; running directory for named

primary 0.0.127.IN-ADDR.ARPA db.127.0.0And a zone entry mapping 127.0.0.1 to "localhost":

You could change the name "localhost" by altering the contents of the db.127 PTR record, but that would be atypical.

By default, when sendmail starts, stock sendmail (no mods to HP's sendmail.cf) probes network interfaces.

The first IP that's found on the first interface gets looked up according to the settings in resolv.conf. The result becomes the setting of the $j macro.

The rest of the IPs on the interfaces are looked up and become class w. (We'll accept mail for domains in class w).

If sendmail can't resolve your host name, set the $j macro in sendmail.cf (Dj$w.Foo.COM)

If you don't want sendmail looking for interfaces that are available, look at DaemonPort Options and DontProbeInterfaces.

BTW, you'll want a correctly functioning DNS to take advantage of the anti-spam features of sendmail.
