Hi I have logged into my maillog file and sometimes there turn errors up. Is there a way to get rid of these errors permanently, so they do not turn up in maillog.. Let me give an example on the errors i want to get rid off : warning: 119.226.93.218: hostname segment-119-226.sify.net verification failed: No address associated with hostname warning: 79.164.26.160: address not listed for hostname host-79-164-26-160.qwerty.ru warning: 122.172.32.67: hostname ABTS-KK-dynamic-067.32.172.122.airtelbroadband.in verification failed: No address associated with hostname warning: 201.102.130.237: hostname dsl-201-102-130-237-dyn.prod-infinitum.com.mx verification failed: No address associated with hostname I have tried to look into cbl.abuseat.org and it seems they are all listed for spamming... In my main.cf i got the following line : smtpd_recipient_restrictions = permit_mynetworks, permit_sasl_authenticated, reject_invalid_hostname,reject_non_fqdn_hostname,reject_unknown_recipient_domain,reject_non_fqdn_recipient,reject_unauth_destination,reject_non_fqdn_sender,reject_unknown_sender_domain,reject_unknown_recipient_domain, check_recipient_access mysql:/etc/postfix/mysql-virtual_recipient.cf, reject_unauth_destination, reject_rbl_client zen.spamhaus.org, reject_rbl_client smtp.dnsbl.sorbs.net, reject_rbl_client bl.spamcop.net, reject_rbl_client cbl.abuseat.org, permit Which means as i read it, that if an address is in clb.abuseat.org it will be rejected. If spam is rejected because of lookup into a rbl it would be nice it does not turn up into maillog file..is there a way in configuring postfix, so this can be avoided ? BR
