Hello Postfix Experts,
I have a FreeBSD 10.1-STABLE system with postfix-2.11.5,1.
# ifconfig
lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> metric 0 mtu 16384
options=600003<RXCSUM,TXCSUM,RXCSUM_IPV6,TXCSUM_IPV6>
inet6 ::1 prefixlen 128
inet6 fe80::1%lo0 prefixlen 64 scopeid 0x1
inet 127.0.0.1 netmask 0xff000000
nd6 options=21<PERFORMNUD,AUTO_LINKLOCAL>
xn0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500

inet 162.217.113.30 netmask 0xfffffffc broadcast 162.217.113.31
inet 199.233.231.176 netmask 0xffffffff broadcast 199.233.231.176
inet 199.233.231.177 netmask 0xffffffff broadcast 199.233.231.177
inet 199.233.231.178 netmask 0xffffffff broadcast 199.233.231.178
inet 199.233.231.179 netmask 0xffffffff broadcast 199.233.231.179
I want Postfix send mail from 199.233.231.177, so I set:
# postconf inet_interfaces
inet_interfaces = 199.233.231.177, localhost
But, the mail log on the destination server says:
Jun 5 13:43:52 barrida postfix/smtpd[54769]: connect from
gtxd.x.rootbsd.net[162.217.113.30]
So, I added to the main.cf file:
# postconf smtp_bind_address
smtp_bind_address = 199.233.231.177
And now Postfix sends mail from the desired IP address, 199.233.231.177.
Jun 5 16:24:47 barrida postfix/smtpd[56193]: connect from
unknown[199.233.231.177]
But I should not need smtp_bind_address set to 199.233.231.177 as
according to http://www.postfix.org/postconf.5.html#inet_interfaces
"When inet_interfaces specifies just one IPv4 and/or IPv6 address that
is not a loopback address, the Postfix SMTP client will use this
address as the IP source address for outbound mail."
Evidently, I'm missing something, would you please help?
