On the SMTP Transport used ("remote_smtp"?) set the `interface` option.
Despite being called "interface", it's actually a list of IP addresses
and the first interface of the correct address family (IPv4 or IPv6)
found is used.

See also $sending_ip_address which is defined for the duration of the
transport.

# in the first section, amongst the macros:
OUTBOUND_IPADDRESS=<; 2001:db8::48:4558:736d:7470 ; 192.0.2.5
OUTBOUND_HELONAME=mx.example.org
#
# then later in the config file

begin transports

remote_smtp:
driver = smtp
interface = OUTBOUND_IPADDRESS
helo_data = OUTBOUND_HELONAME
