but you *always* need to provide configurations with consistent replacements of not to disclose informations, otherwise no help is possible you see below why > - First: in main.cf I added 'sender_dependent_default_transport_maps = > hash:/etc/postfix/sender_transport' > - Second: I create /etc/postfix/sender_transport with lines looking like: > '@3dn.nl smtp3dn:' > - Third: I ran postmap on the sender_transport file > - Fourth: I added a line 'smtp3dn unix n - n - - > smtpd -v -o > smtp_bind_address=172.24.25.19' to master.cf smtp3dn unix n - n - - smtpd -v -o smtp_bind_address=172.24.25.19 smtpd is wrong because you are talking about *outgoing* mail and this is the smtp client as well as your param starts with smtp_ and not smtpd_ smtp != smtpd smtp3dn unix n - n - - smtp -v -o smtp_bind_address=172.24.25.19 may work better, ignoring other details for now
