You have no PTR record for your domain cig.co.ae if that is the domain
that you are trying to send from. Sun is using sendmail to deliver mail
and sendmail reject any unresolved domain name or domain without PTR
record.
How I am searching:

No PTR records exist for cig.co.ae. [Neg TTL=3600 seconds]
Details:
