Couldn't use a virtual mailbox or virtual alias domain? Well - The problem is that I have several "official" domains and for the sake of order when sending mail - the IP-Address used for sending should match the MX-record. When I'm not mittaken, the only way for having a certain IP address used while sending from a certain mail-domain is to use multiple instances of postfix. >> When starting the second instance "postfix -c /etc/posfix2 start" >> maillog logs: >> >> Oct 14 15:30:45 OpenBSD42 postfix/master[11315]: fatal: open lock file >> /var/lib/postfix/master.lock: unable to set exclusive lock: Resource >> temporarily unavailable >> > Postfix 2.5 added the data_directory parameter. > (http://www.postfix.org/postconf.5.html#data_directory) > This refers to the /var/lib/postfix in many installs. I stumbled across "data_directory" but it was not realy clear if an can just modify that paramter for the 2nd .. or 3rd instance pointing to a different data directory ... > Brian Kind regards, Stefan
