Exchange Addon to do Sender Based Routing

[Christoph Schmidt]

Sender Based Routing IS possible with Exchange 2007 and 2010 with an addon tool called ptecs EXSBR. ExSBR is a Hub Transport Agent which extends routing possibilities in Exchange Server. It is able to route by sender's smtp domain name or AD group memberships.

You can get an eval version from me, if you want to. Just write an email to exsbr at ptecs dot de with the number of your mailboxes, servers and hub transport servers.

Kind Regards,

Christoph from ptecs GmbH in Germany

Hi Sarath,

Thanks for your reply and explicit explanation.

I fully understand you concern. However, as far as I know, for Exchange
2007 server, it will use different routing method like DNS or SmartHost
server to send outbound mails based on the REMOTE email domain that emails
are sent to, instead of the ACCEPTED email domains which emails are sending
from. I.E. Exchange server will NOT route the mails based on sender's
domain.

However, I am stilling researching for any possible work around. I will get
you posted here on this issue.

If there is anything unclear, please let me know. Thanks!

Best regards,

selective domain SMTP through a different gateway
We are hosting about 17domains in a single exchange 2007 server. The mails
were relayed by an Antispam box. However it had issues in relaying and hence
the relay was reverted to exchange server.

Now instead of switching the whole relay of mails to anti spam box, we would
like to choose few domains mail to be relayed through this box for testing
purposes - how can we do this?

Hello kannan,

Thanks for your post and Andy's input.

As I understand that your Exchange server 2007 hosts 17 email domains
(multi recipient policies) and previously you used a 3rd party "Antispam"
mail server to relay for your 17 email domains. Since the "Antispam" mail
server has some problem, you would like to use the "Antispam" mail server
relay for part of your 17 email domains for outbound email routing and
other email domain still use your Exchange server for routing when sending
outbound emails.

If I have misunderstood the problem, please don't hesitate to let me know.

If it is the case, I would like to know how did you configure your Exchange
server to be relayed by the "Antispam" mail server previously? And if the
"Antispam" mail server is also using Exchange server 2007 and how it is
configured to relay for your 17 email domains? Can this issue be resolved
from the "Antispam" mail server side?

Generally, Exchange server will use different routing method to send
outbound mails based on the remote email domain that emails are sent to,
instead of the hosted email domains which emails are sending from.

Hope this helps. Also, if you have any questions or concerns, please do not
hesitate to let me know.

Hello Robbin, Please let me explain the scenario.
Hello Robbin,
Please let me explain the scenario.As you understood we have 17
accepted domains.Initially we have routed all the mails through the
Anti-spam,which is using a third party application.For this we have created a
send connector for all address space and to route mails through a smart host
,Anti-spam.
But we came to know that there is some problem with the anti-spam
in routing the mails.So we configured the Exchange server to route the mails
using DNS look up (MX Record).
Now we want to route the mails through anti-spam box.So instead
of going for all Accepted domain we want to know whether it is possible to
route some the accepted domains through the anti-spam box.
ie is it possible in exchange server to route the mails based on
sender's domain through a smart host.Suppose I have xxxxx.com as accepted
domain ,is it possible to route the mails (outbound) from this domain through
a smart host?

Please clarify.

Thanking You
Sarath.

There exists a tool named RouteBySender that implements conditional routing of outgoing emails.
