UK postal orders are issued in sterling pounds only. Maybe you could get an International Money Order to the value of the exchange rate on the day. I am not sure what you mean when you say 'how to receive' it.
Thanks for your answer. What I mean "to receive" I mean that someone is sending me postal order from UK ...should I go to post office? my bank?or any other bank?
I know for a fact that the GPO in Dublin cannot cash a UK postal order issued in sterling pounds. I would say you will have to lodge it your bank account. Phone your bank and they will give you a clearance time. Hope this helps.
