Exim config to route email to certain domains through another provider?

[unco]

Hi folks,

There's a regional bank with which a ton of people in our area do business. We route all our mail out through SpamExperts. The bank has a rule on their Barracuda ESS that prohibits any mail from a non-US IP address from being delivered to their accounts. I have tried numerous times to contact them by phone and by email, but they never respond. I have asked my customers to contact them. Apparently, they will whitelist individual email addresses if the customer complains. However, we have customers who are attorneys, accountants, realtors, etc (lots) who need to do business with them.

I would like configure Exim to change the route for any mail destined for thelocalbank.com to go out through another provider we use.

The logic would be as follows:
If TO or CC contains @thelocalbank.com, then send through smarthost2.

Has anyone done this and knows a config that works?

Thanks in advance,
Beth

There are a great deal of threads on this subject already in the forums, for example:

Forward certain domain emails to Smart Host

THis is my first post. I got an SMTP.COM account and I want all my mails to route through them as a smarthost. However they require smtp authentication, so far I know how to relay mail to their server but not how to authenticate it.

Smart-Host for a single domain among many in WHM

Hi I have 10 different domains on my WHM (D1, D2,D3 ... D10), all are working fine, sending and receiving email as well. I need to configure only one domain (say D1) to use a smart-host to send its mail (as shown in the figure below) while the other domains should continue to send and receive...

Hi Lauren,

What I mean is to have @something.com be sent out through another server, even localhost. I do already have routing set up for entire domains to be routed out through a particular host or hosts, but, in this case it is the destination domain I want to route.

If destined for something.com, send out through localhost or some other smarthost.
Otherwise, send out through designated smarthost.

I will do further research and try a few things. I'll let you know what I find.

Thanks,
B

Within the confines of WHM's editor, I think you can use a static route.

static_route:
driver = manualroute
transport = remote_smtp
route_data = ${lookup{$domain}partial-lsearch{/etc/staticroutes}}

Then in /etc/staticroutes you specify your route.

bankdomain.com: SMARTHOST_IP

You put this after the POSTMAILCOUNT section.

See: EXIM relay only if recipient is at hotmail.com for more info.
