ok i have solved this issue by using the 587 port instead of the 25 to send mail on the server.

i post it in case it can help somebody.

cheers.

Glad to hear you solved the issue for your store!  I've run across this a few times as well.  Thought I would share a bit of background on why changing the port from 25 -> 587 got your mail flowing again...

It would appear the primary reason is that traffic on port 25 is not encrypted and sent entirely in plain text - by changing the port to 587 you are going to be using TLS & encrrypting the message communications between your Magento app and the Mail Transfer Agent that will be relaying your outbound SMTP mail.  That's better for everyone.

I'm including a few reference links below on the differences between the ports and how they're traditionally used:
