Installer issue

[os13]

Hi,

I have installed Roundcube on a DS710+ synology NAS (V3.2).
Everything went fine until the third screen of the installer :

When testing SMTP, I have this message : SMTP send:  NOT OK(Invalid sender or recipient)
My email address is OK in both Sender and recipient.

Also, when by-passing test in code (test.php -> "if (preg_match('/^' ..." change for "if (1)"), I have another issue:
SMTP send:  NOT OK(Connection failed: Failed to connect socket: $addr cannot be empty)

Imap test doesn't work, also : IMAP connect:  NOT OK

Once again, I'm sure of my Email address, password and server address.

If I try to connect to the Webmail, I have a connexion to IMAP server Error.

I've tried V0.6 and V0.7 Beta  (installed from scratch), with the same errors.

Is Anybody successfully install RC on a synology ?
