I'm having an issue getting the smtp client to bind to an aliased IP
address.
mail_version = 2.5.7
I've tried to no avail to have the smtp client use a aliased IP to
deliver mail but it insists on using the address of the interface the
aliased address is assigned to.
# ifconfig eth2 && ifconfig eth2:1
eth2 Link encap:Ethernet HWaddr 00:15:17:6f:e6:1e
inet addr:142.22.75.146 Bcast:142.22.75.151 Mask:255.255.255.248

I've tried the following in main.cf ...
smtp_bind_address = 142.22.75.147
I've also tried the following in master.cf ...
smtp unix - - n - - smtp
-o smtp_bind_address=142.22.75.147
Reading a correlation between smtp_bind_address and inet_interfaces in
the docs I've also tried the following in main.cf ...
inet_interfaces = $myhostname, localhost
With the later netstat shows master binding to the aliased address
142.22.75.147 and 127.0.0.1 and the smtpd server receives mail fine on
the aliased address however the smtp client persists in using
142.22.75.146 to deliver mail to other hosts.
tcp 0 0 127.0.0.1:25 0.0.0.0:* LISTEN

tcp 0 0 142.22.75.147:25 0.0.0.0:* LISTEN
27605/master
What am I missing?
Thanks
