Hi there, I set up a VM a couple of weeks back as a mail server. I can send email via web mail and I can get email in but I can't get it to relay. cat /etc/postfix/main.cf | grep restrictions # overcome chroot restrictions. The alternative, having a copy of # through Postfix. See the smtpd_recipient_restrictions parameter # relay mail to. See the smtpd_recipient_restrictions description in smtpd_relay_restrictions = permit_mynetworks,permit_sasl_authenticated,reject_unauth_destination mua_client_restrictions = permit_sasl_authenticated,reject mua_helo_restrictions = permit_sasl_authenticated,reject mua_sender_restrictions = permit_sasl_authenticated,reject smtpd_recipient_restrictions = permit_mynetworks,permit_sasl_authenticated,check_policy_service unix:/var/spool/postfix/postgrey/socket smtpd_recipient_restrictions = reject_invalid_hostname, reject_unknown_recipient_domain, reject_unauth_pipelining, permit_mynetworks, reject_unauth_destination, permit_sasl_authenticated, check_policy_service unix:/var/spool/postfix/postgrey/socket, reject_rbl_client zen.spamhaus.org, reject_rbl_client bl.spamcop.net, reject_rbl_client dnsbl.sorbs.net, reject_rbl_client cbl.abuseat.org, reject_rbl_client b.barracudacentral.org, reject_rbl_client dnsbl-1.uceprotect.net,permit cat /etc/postfix/master.cf | grep restrictions -o smtpd_client_restrictions=$mua_client_restrictions -o smtpd_helo_restrictions=$mua_helo_restrictions -o smtpd_sender_restrictions=$mua_sender_restrictions -o smtpd_recipient_restrictions=permit_sasl_authenticated,reject # -o smtpd_client_restrictions=$mua_client_restrictions # -o smtpd_helo_restrictions=$mua_helo_restrictions # -o smtpd_sender_restrictions=$mua_sender_restrictions # -o smtpd_recipient_restrictions=permit_sasl_authenticated,reject -o smtpd_client_restrictions= -o smtpd_helo_restrictions= -o smtpd_sender_restrictions= -o smtpd_recipient_restrictions=permit_mynetworks,permit_sasl_authenticated,reject Any ideas?
