Email not being sent locally, but being sent globally

[Michael E. Collins_1]

I am running hp-ux 11.0 on a RP5470, I am trying to send emails to people inside of network. When i do sent them emails They dont receive them, I can send to external places yahoo, hotmail etc etc. I am looking for any ideas, thoughts, or hints as to what might be wrong.
Thanks in advance.

Well they must be going somewhere.
Can you look at the mail log file, usually in /var/adm/syslog/mail.log, and the system log, in /var/adm/syslog/syslog.log.

I expect you will find some pointers there.

Does the "mailq" command show anything ?

Hi,
When you send mails internally what's error
logged /var/adm/syslog/mail.log ?

Possibly sendmail.cf Dj macro to be set correctly.

Revert with
/etc/mail/sendmail.cf
/etc/mail/sendmail.cw
/etc/mail/service.switch

/etc/resolv.conf
/etc/nsswitch.conf

/var/adm/syslog/mail.log

To see where they are going:

/usr/lib/sendmail -v
test
^d - yes, this is Control d to send.

If local delivery due to local accounts
they will be in /var/mail/.

If you are running NIS and have an NIS
aliases map or even local /etc/mail/aliases
then the sendmail test above will show you
the aliased to address.

You also have to check /etc/mail/sendmail.cf
for the line:

DS

Which is the smart relay. Your emails may
be getting routed to another system in the
network that is either delivering them
to the wrong system or /dev/null.
The test above will also show which system
it is connecting to and other useful info.

Use these tests to see how sendmail is configured, to where it is sending mail, and how it choses a mailer:

sendmail -d0 -bv user@domain

sendmail -bt
/parse user@domain
^D

Set LogLevel=13 in /etc/mail/sendmail.cf so sendmail will tell you everything you need to know in /var/adm/syslog/mail.log (or whereever syslogd is sending LOG_MAIL). Do not set LogLevel any higher or sendmail will generate debug notes to LOG_DEBUG that only a developer would understand.

If your domain has MX records defined in private DNS, you could set the Smart Host to just the domain name (DS$m) and let the MX hosts deal with all the outbound traffic.

If your server is not intended to be a mail relay or repository, you should also set DH$m, DR$m, and DM$m, forcing the MX hosts deal with ALL mail.
