I try the google and a propetary SMTP.

Hi Cerelli,

You need to ensure the SMTP details are correct. Have you verified them with your host? Do they work in other SuiteCRM versions?

Thanks,

Will.

I try with suitecrm 7.1.5 is ok.
What can i do ?

With the same settings, in 7.2 beta3 the error is:
Errore email:SMTP Error: The following recipients failed: aaaa@aaa.it
