Postfix problem

[theprincy]

I solved by changing in this way


# SASL paramters
smtpd_sasl_auth_enable = yes
smtpd_sasl_security_options =
smtpd_sasl_local_domain =
broken_sasl_auth_clients = no

smtpd_helo_required = no

smtpd_helo_restrictions = permit_mynetworks,
permit

smtpd_sender_restrictions = permit_mynetworks,
permit

smtpd_recipient_restrictions = permit_mynetworks,
reject_unauth_destination

smtpd_data_restrictions = reject_multi_recipient_bounce,
reject_unauth_pipelining


thanks for the tip
