Hi, I got a setup working now where a user can only send mail with his mail address, gets authenticated at the SMTP server with his IMAP credentials suing dovecot and mails get be send to different relay servers depending on the senders address. I have these postfix settings: smtpd_sasl_path = private/auth smtp_sasl_security_options = noanonymous smtpd_sasl_auth_enable = yes smtp_sender_dependent_authentication = yes sender_dependent_relayhost_maps = hash:/etc/postfix/maps/relayhost smtp_sasl_auth_enable = yes smtp_sasl_password_maps = hash:/etc/postfix/maps/password smtpd_client_restrictions = permit_sasl_authenticated smtpd_sender_restrictions = reject_sender_login_mismatch smtpd_sender_login_maps = hash:/etc/postfix/maps/login With those SquirrelMail can authenticate at the SMTP server. regards, Hendrik ------------------------------------------------------------------------------ LogMeIn Rescue: Anywhere, Anytime Remote support for IT.
