Hello,
the following patch modifies transports/smtp.c to use the first address
of local_interfaces if these are explicitly configured as the source for
outgoing SMTP connections. This is used here in a setup which
needs multiple really idenpendant instances of exim running on one host.
There should be no negative side effects.
The patch has not been done for the HAVE_IPV6 case yet.
Please direct any comments etc. also to me as I have not subscribed to
this list.
Regards,
Lutz
