Hi, I saw something strange these days. the server is runnig under FreeBSD I try explain using 10.0.0.0 networks, ther real ip are real ips with no NAT. The base plesk server is 10.0.0.X and have some domains in shared mode. But have some more domais in the same machine with own ip address ( to offer ftp and tunne badwith in firewall ) like pleskserver.com - 10.0.0.X domain1.com - 10.0.0.a domain2.com - 10.0.0.b domain3.com - 10.0.0.c domain4.com - 10.0.0.d domain5.com - 10.0.0.e domain6.com - 10.0.0.f The problem is: The client using the domain5.com (10.0.0.e) is woking fine the http/https/smtp(in)/pop/imap all working perfect. but all email smtp(out) is going from the base IP (10.0.0.X)address and not from domain5.com (10.0.0.e) ... in this way i must trotlle all connections to this machine and not only to the domain5.com. There is some tunning, adjust in qmail or other point to make the smtp(out) from domain5.com use every time the right IP (10.0.0.e) and never the main IP ( 10.0.0.X) TIA.
