Hello! I have a server running FreeBSD 8.1 with FreeBSD 8.1 jails running on it. I have ipv6 running on both the main server and jails and that is all fine.
I'm running into a strange problem when it comes to postfix though and was wondering if anyone has any clues. What's happening is that postfix will not start automatically when the jail is started when 'inet_protocols' is set to either 'all' or 'ipv4, ipv6'. The error in the logs is: fatal: bind :: port 25: Can't assign requested address. The odd thing is that I can enter the jail right away and start postfix from the command line and it works fine. Also, if I specify the '-D' flag in rc.conf and set the debug command in main.cf to 'sleep 3' then postfix will start automatically when the jail is started. I've also tried setting 'inet_interfaces = loopback-only' in main.cf which gives the following error in the log: fatal: /usr/local/etc/postfix/master.cf: line 22: no valid IP address found: smtp And setting '127.0.0.1:smtp ...' in master.cf works but then postfix only listens on ipv4: tcp4 0 0 jailhost.ssh *.* LISTEN tcp6 0 0 jailhost.ssh *.* LISTEN tcp46 0 0 *.http *.* LISTEN tcp4 0 0 jailhost.smtp *.* LISTEN Setting '[::1]:smtp ...' in master.cf does not work. This is the error in the mail log: fatal: bind :: port 25: Can't assign requested address I've read through the postfix manual, looked around online and tried many different settings but nothing works (besides that hack of running with the -D flag). I'd super appreciate any help or any ideas anyone may have. If more info is needed please let me know and I will post.
