Changes to Banco Posta?

I am having problems tranferring funds between my BancoPosta current account and my Geometra's account, also with BP. Not had this problem before and respective bank details have not changed. Following the same process as before I get a message saying

"Impossibile eseguire un bonifico esterno verso un conto Bancoposta".

I wondered if tightened regs over movement of money may have passed me by, though note my BP is registered in Italy and accessed online through a UK ISP.

Grateful for any thoughts on the likely problem - e.g. maybe BP's site is just not working properly - as my Geometra is waiting on his payment!
