Probem "solved".
I reactivated the secondary/backup MX ( Exim version 4.50 ) server and now
the messages are arriving without problems trough the secondary MX.
May be there are some strange network problems between some net or some
problems with exim6.0.
We are in Italy, the secondary MX is in the USA.
So the messages now make bigger travel but without problems.
I remain in doubt about a possible exim problem.
The main SMTP is Exim version 4.60
thanks
