Hi all,
I use roundcubemail since years, I am running it on the latest Centos.

As soon as I upgraded it to the 1.3 version I can't send email anymore using phpmail.

When I try to send an email it says:
"SMTP Error (554): ... "email@email.it" non riuscito (5.7.1 <sblan@email.it>: Relay access denied)"

Can you help me please?

Thanks.
