hostname is appended to domain with email

[Terrence]

I have a server called "python" with HPUX 11.23. I have an account called "alert". My domain is chicomhos.org.

I have various monitoring scripts that send emails for events.

When the account "alert" sends email from those scripts it appends "python" to the domain so the address become alert@python.chicomhos.org

How do I prevent the server name from being included so the email just says alert@chicomhos.org?

My default domain is set correctly in /etc/resolv.conf.

One of my vendors cannot receive these emails because it cannot resolve the (nonexistent) domain of python.chicomhos.org

Hi Terrence

You will need to do masquerading, with this all mails will go thru the server as chicomhos.org

Hi,

You can either use macros DM in /etc/mail/sendmail.cf or run
cat message| sendmail -f alert@chicomhos.org myvendor@someth.com

Edit /etc/rc.config.d/mailservs and configure:

Edit the file /etc/rc.config.d/mailservs:
SENDMAIL_SERVER=0
SENDMAIL_SERVER_NAME="domain.com"


Or change /etc/mail/sendmail.cf


# my official domain name
# ... define this only if sendmail cannot automatically determine your domain
#Dj$w.Foo.COM
Djdomain.com

As a heads-up to everyone, if you send email notifications to pagers or cell phones you will probably need to make this change.

We kept encountering more and more companies that would not deliver our pages without being able to resolve the 'from' domain. (They were being adddressed exactly as Terrence described).

Scott,

I've had that very problem of not being able to send to beeper companies. Please clarify, you posted that we'd probably "have to make this change." Which of the "these changes" above do we have to make?

For the record, the correct answer to my issue was to "mascarade" my domain.

This is done via /etc/mail/sendmail.cf. Here is the piece I edited.

# who I masquerade as (null for no masquerading) (see also $=M)
DMchicomhos.org

I had similar issues a while back.
