can not send email - SMTP error on roundcube

[wolvepy]

Now it's partially solved.
I can send (unfortunately it falls in the spam box) but I can not receive.

What I did is:

Code:

sudo dpkg-reconfigure postfix

And follow the instructions.
This solved the problem of the port, but not the smtp server.
For smtp I edited /etc/postfix/main.cf file with:

smtpd_sasl_type = dovecot
smtpd_sasl_path = private/auth
smtpd_sasl_auth_enable = yes

I can send but not receive.
