[Dovecot] Rejected mails

I'm getting closer, now with SMTP permitted to whole of Internet to
connect to my SMTP/postfix server & for my postfix server to
connect out to public Internet on tcp 25 as well.

I send emails from permitted domain's SMTP servers with "Receipt
Acknowledgemt" & the ack returned said it was delivered but somehow
there's no mail in the mailbox & using the site below to test, it gave
Rejected :

http://legacy.zoneedit.com/whois.html

OK, connected to gate1.mds.com.sg...
< 220 gate1.mds.com.sg ESMTP
> HELO edit.dnsvr.com
< 250 gate1.mds.com.sg
> MAIL FROM:<sender_id at mds.com.sg>
< 250 sender <sender_id at mds.com.sg> ok
> RCPT TO:<recipient_id at myportaltech.com>
< 550 #5.1.0 Address rejected.


The recipient_id is basically a Linux OS id in my SMTP server.
Would this work or I'll need to have virtual domain ids ?
