Hi Pramod,

You need to contact pharmetics.com exchange team to check the receive settings.
Their firewall may be blocking the emails from your domain.

Hi,

that error means that your server has managed to reach pharmetics server, but it did not find that specific user.
Maybe that user has been deleted/ disabled/ something with it? Can you send to any other user from that pharmetics domain?

Your SPF record does not have anything to do with it.

Regards,
Ivan.

that user exists and he has active mailbox, in fact email to any user gives same error.

the email to any user in that organization goes through fine from Hotmail or any other personal account

and he says he has been receiving emails from all other external organization.

Hi Pramod,

Please tell them to allow your domain into their firewall.

Sounds like some anti-spam settings on the recieving system is preventing emails reaching them from your domain.

It's worth checking to ensure your reverse dns and spf records are correct.

If  your records are correct, try to see if their IT department/administrator can check their SMTP logs for the reason why it's refusing emails from your domain.
