sendmail to external mail-id not working --- 550 Relaying denied

[prasanth.vattoly]

We have a HP-UX B.11.11 server.

In this sendmail is not working for external mail-ids (like prasanth.vattoly@gmail.com ). But it working for internal company mail ids.

We had configured the sendmail as we done on the other servers.

Attaching the logs of sendmail command along with this mail.



THanks In advance
Prasanth

Shalom,

corpsmtp01.companyconnect.com. via relay...

This system is not permitting relay.

It should be configured by IP address or hostname to permit relay from this host.

Its not a problem on the HP-UX system as far as I can tell.

Did you define the DS variable for the relay server.

#grep ^DS /etc/mail/sendmail.cf
DSbiharprd.companyconnect.com

If your mail server is biharprd.companyconnect.com then you should be able to ping/nslookup the biharprd.companyconnect.com
