Re: How to allow mails from some other servers to pass: reject_sender_login_mismatch
Hi, yes, you are right using mynetworks is ok. I also though for this way. I just didn't understood from beginning why it didn't work with access file, but now is clear. Thanks!

How to allow mails from some other servers to pass: reject_sender_login_mismatch
Hi, i'm trying to slow down and block backscater mails and i try to use: reject_sender_login_mismatch and smtpd_sender_login_maps. I have some questions about how to pass this restriction for some cases. The situation is this: We have some other servers where we have installed other webapplication that send mail from there using for example i...@ourdomain.com without authentication. These mails are sending to our mail server, but now we filter all these addresses to prevent using our addresses in MAIL FROM to send mails to us. How to allow these servers to pass the rule reject_sender_login_mismatch? We have this configuration for sernder restrictions: smtpd_sender_restrictions = permit_mynetworks, permit_sasl_authenticated, check_sender_access hash:/etc/postfix/access, # reject_sender_login_mismatch, reject_non_fqdn_sender, reject_unknown_sender_domain, reject_unauth_pipelining, permit i have commented out the parameter, temporary until i find out how to solve this problem. I added in access file this kind of entry: serveripaddress OK but this does not help, i got mailer-daemon mail when other server sent mail. Thanks in advanced! Regards, Ali Nebi!
