Just added a rule to postfix's config file to try and clean up some of the trash going through the server, namely:
smtpd_helo_restrictions = permit_mynetworks, reject_unknown_hostname, reject_invalid_hostname, reject_non_fqdn_hostname, permit smtpd_sender_restrictions = permit_mynetworks, reject_invalid_hostname, reject_unknown_hostname, reject_unknown_sender_domain, reject_non_fqdn_hostname, reject_non_fqdn_sender, permit which are definied as: # reject_invalid_hostname: reject HELO hostname with bad syntax. # reject_unknown_hostname: reject HELO hostname without DNS A or MX record. # reject_non_fqdn_hostname: reject HELO hostname that is not in FQDN form # reject_non_fqdn_sender: reject sender address that is not in FQDN form # reject_unknown_sender_domain: reject sender domain without A or MX record. that should weed out some garbage before it gets into the queues ... or those users with mis-configured servers ... so, if you are legit, and trying to send an email through that is being rejected, take a look at the above as potential causes ... ---- Marc G.
