Long time ago I have succeeded to hide my local ip using qmail when I was sending emails from my home.
In that configuration I had only to modify tcp.smtp to have something like:
xxx.xxx.xxx.xxx:allow,RELAYCLIENT="",TCPREMOTEIP=""
In this Plesk configuration it is a pain that I cannot do this type of hidding.
So, because Plesk uses for qmail just tcp-env I cannot use that tcp.smtp file.
However, I am really interested into this as I really feel it should be something easy to modify in order that for all emails that I am allowed to relay (user&pass correct) the ip should somehow be hidden.
Again, I am interested about this only for 1-2 IP's that I use it from home.
Thank you for ANY idea you may have.
