Re: transport_maps and lookups reason

Thank you. 2. "source@emal" Can source email (mail from) lookup be disabled when using transport_maps? Any ideas? As I understand transport_maps should rely on destination address when sender depended transport maps are not used. 15.05.2018 20:48, Viktor Dukhovni пишет: 2. "source@emal"

Hi, sounds like you want If from ( benachrichtig...@cubewerk.de) and from (10.8.1.1-3) Then allow Else REJECT Sounds like you would need a regex expression to catch two conditions and then act on it. Not sure postfix can store result of first check and
