Thank you so much for your tips. I really do appreciate. I have read of course the docs for many times before trying to implement it but it still does not work. I could've missed something somewhere. I will keep on trying though. You are saying that "there is only one action allowed per header". I guess this is the reason why it does not work. My /^User-Agent: .*/ IGNORE triggers and all the other rules like /^Received: .*/ IGNORE /^X-Originating-IP:/ IGNORE and so on are not taken into account/consideration then and therefore do not work, is that right? Plus, you mentioned in your other post that header_checks and smtp_header_checks if used together may mangle each other and conflict? Did I understand you correctly? I will toggle them just to test and to check if that could be the reason as well... I haven't tried yet to use either header_checks or smtp_header_checks only. I have always used them both at the same time. Would be thankful for any further comments. -- View this message in context: http://postfix.1071664.n5.nabble.com/Stripping-Received-headers-tp56953p86997.html Sent from the Postfix Users mailing list archive at Nabble.com.
