Use remote smpt server

[gersonfs]

Hello!

How can I configure exim to use a remote smpt server for sending e-mails?
I ask because we are having problems with hotmail and yahoo, we are in a blacklist them. So I would like to authenticate with that problematic server, but use another server for sending messages, how to do this?

Sorry my bad english!

Thanks!

You would likely want to use a smart host router to route the emails:

Mailing List Archive: Router/Transport Problem with multiple entries

You'd need to create a file called /etc/staticroutes with the following:

domain1.com: IP#
domain2.com: IP#
domain3.com: IP#
and so on

Or, the following in the file:

domain1.com: mail.location1.com (the MX record pointing to the off site server)
domain2.com: mail.location1.com (the MX record pointing to the off site server)
domain3.com: mail.location1.com (the MX record pointing to the off site server)
and so on

Next, you would need to go to WHM > Exim Configuration Editor > Advanced Editor and locate the routers area there, then put this into that routers box:

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

At that point, you'd then locate the transports section in the Advanced Editor for exim and place the following:

remote_smtp_smart:
driver = smtp
port = 25
delay_after_cutoff = false
hosts = ${lookup{$domain}lsearch{/etc/staticroutes}}
hosts_override

Save that area, then test sending an email as one of the domains to see the results.
