List, I use Postfix and I have active the rule of "header_checks." In the list of "header_checks" I have some 1200 addresses of spammers, inside which there is a couple that they are of here of the it lists (in fact they have addresses of servers that allow the one open relay, and I prohibit the entry of those "whole" servers). That makes that on one hand never receipt the messages of partners of the list that they have their address in those servers. On the other hand, every few days I receive announcements that my e-mails they are bouncing. I was trying of enabling so that "everything" what comes with "sender" "@suse.com" it allows it to happen "ignoring" the header_checks. In fact it is not the "sender" but the "recipient", since in the sender field comes the person that wrote and in the recipient field comes "@suse.com." I was playing with smtpd_client_restrictions, smtpd_recipient_restrictions and smtpd_sender_restrictions... ... but seemingly "always" it is applied the rule first of "header_checks", therefore it is useless all that I put in those other restrictions. You have idea of how to make so that leaving the @xxx.yyy in the list of header_checks, to authorize on the other hand so that it allows to pass the mail still if one of the recipients is xxx@suse.com? -- Greetings, Alberto mailto:linux@opc.com.uy Linux User #242064 UyLug Member #195 -- Alone there are 10 types of people.
