Yes - your server's domain does not exist - taca.com - atleast the server 172.17.16.61 doesn't think so...

Where does the first one (sendmail -v) go to? same server 172.17.16.61?

Also - where are you telneting from - is that server in the taca.com domain? If not - then you need to set the DM macro in sendmail.cf to taca.com

sendmail -v goes to other server.

I am using telnet to oratan1a itself

[Geoff Wild]

Well...taca.com does have an A record and MX records - but I see NO A record for oratan1a.taca.com...

So, as I said above, try setting the DM macro on oratan1a to DMtaca.com

stop/start sendmail

I change macro DM to DMtaca.com... same problem.

Where is the MX record on HP-UX?

[Geoff Wild]

MX records are in DNS...

Anthying in /var/adm/syslog/mail.log ?

[Edwin Ruiz_2]

This is a piece of /var/adm/syslog/mail.log

thx

In /etc/hosts, try adding the fully qualified domain name to oratan1a

172.17.16.61 oratan1a.taca.com oratan1a

same problem... Do i need some patch for sendmal?

[Geoff Wild]

What do you get when you do:

nslookup -q=MX taca.com

I open a call on HP and we did this procedure

# cd /user/newconfig/etc/mail/cf/cf

# ./gen_cf


# cp sendmail.cf.gen /etc/mail/sendmail.cf

all is working now
