Hi All, I have a problem sending and receiving emails. I can logon to squirrelmail, but it won't allow me to send emails. When setting up a client, the test fails when authenticating for SMTP. (Yes I logon to the SMTP server with my UID /PW and use the auto detect TLS / SASL) This is the error message in the mail error log: Sep 27 14:47:08 postfix/smtpd[1032]: fatal: parameter "smtpd_recipient_restrictions": specify at least one working instance of: check_relay_domains, reject_unauth_destination, reject, defer or defer_if_permit And this is what I have included in the postfix main.cf smtpd_recipient_restrictions = permit_mynetworks, permit_sasl_authenticated, check_recipient_access mysql:/etc/postfix/mysql-virtual_recipient.cf see the whole main.cf file below. ================================= # See /usr/share/postfix/main.cf.dist for a commented, more complete version # Debian specific: Specifying a file name will cause the first # line of that file to be used as the name.
