Hi !! Question : Are the fowarded emails scanned about virus and spam ? I've got a user with forwarded adress, and the receiver smtp server block mine for 24h as too many spam sent. Note that I've already install postfix checks (helo, fqdn and so on), and then also install postgrey. Still same message from smtp or the provider where I forward mails for that user. Thanks !
That is what I was thinking. Do you think it could be a good idea to implement it ? Also, I've been unbanned since I'm using in main.cf of postfix : -basics checks -black lists -grey lists Some of they are quite usefull and easy to deploy (checks and blacklist), would it be a nice idea too to implement these ? (at least the checks) here's the relevant parts of my main.cf : Code: # SPAM smtpd_delay_reject = yes smtpd_require_helo = yes smtpd_helo_restrictions = reject_non_fqdn_hostname, reject_invalid_hostname, permit smtpd_client_restrictions = permit_sasl_authenticated, permit_mynetworks, reject_rbl_client bl.spamcop.net, reject_rbl_client zen.spamhaus.org, reject_rbl_client safe.dnsbl.sorbs.net, reject_rbl_client cbl.abuseat.org, reject_rbl_client list.dsbl.org, permit smtpd_sender_restrictions = reject_non_fqdn_sender, reject_unknown_sender_domain, permit smtpd_recipient_restrictions = permit_sasl_authenticated, permit_mynetworks, reject_unauth_pipelining, reject_non_fqdn_recipient, reject_unknown_recipient_domain, reject_unauth_destination, check_policy_service inet:127.0.0.1:60000, permit
Yes, this makes no differense. the forwarding is done by postfix and the procmail recipes that do the spam scanning are invoced later. For local accounts, it is not such a big problem as the spam scanning can be done in the target mailbox.
Yes, but if i setup forward to few local accounts, spam scanning occurs as many times as many addresses i will put in forward rule - instead of only one spam scanning job.
Sure. But if spam scanning would occur before the forwarding, the email will be scanned even one time more as scanning the email before the forward would not prevent the svanning at the recipient accounts.
