Hello everyone ! I'm trying to achieve a simple thing. Then user logins via SASL and sends mail, I want postfix to check that SASL login is identical to MAIL FROM filed.
As I can see, I can do that with 'reject_sender_login_mismatch', but usage of this option implies usage of 'smtpd_sender_login_maps'. The problem is that I use MS AD as user list provider, so firstly, I thought about some tricky filter to achieve this, but I can't think up something workable. Second option is to create some hash 'file' and fill it with maps, but truly speaking I don't want to do this because it's a manual work. Of course, I may do some script to download info from AD and put it to the file. However, maybe another options exist too ? I don't need user to be able to write as another user, so simple variable comparison like '$sasl_user == $mail_from' would be a prefect match. Thanks in advance. -- Best regards, Mate200
