We do something similar except we actually select IP based on
domain not individual sender. The following config is therefore
untested but I have just replaced $sender_address_domain with
$sender_address.
Change the remote_smtp driver (assuming you still have this named as
default) to
remote_smtp:
driver = smtp
interface = ${lookup{$sender_address}lsearch{/path/to/file/interfaces}
{$value}{aaa.aaa.aaa.xxx}}
helo_data = ${lookup{$sending_ip_address}lsearch{/path/to/file/mailhelo}
{$value}{mailout-default.domain.com}}
(This may line wrap when displayed - everything after interface = and
helo_data = are on one line each)
where /path/to/file/interfaces contains
[email protected]: aaa.aaa.aaa.aaa
[email protected]: aaa.aaa.aaa.bbb
aaa.aaa.aaa.xxx is the default IP to use for senders who do not appear
in the file.
and /path/to/file/mailhelo contains
aaa.aaa.aaa.aaa: mailout-aaa.domain.com
aaa.aaa.aaa.bbb: mailout-bbb.domain.com
Again mailout-default.domain.com is the entry for the default IP.
These names should correspond to whatever a reverse DNS lookup of the
relevant IP gives. Omitting this means your HELO string will be wrong
for connections not using the default interface. (An alternative to
this is to have the reverse DNS look up to the same name for all
outgoing IPs)
Hope this helps.
