Can Excange 2007 handle thousands of emails at once?   

Hello,

in our organisation we would like to send an annual email to 60.000
customers. These emails will be sent from an Oracle application,
through our Exchange 2007 server (multiple roles), to external
recipients.
I was wondering how many emails can be sent at once? Is there a limit
Exchange 2007 can handle (like 500 emails per minute), or will
Exchange 2007 queue the emails (so I can send all the 60.000 at once)?
I am aware I can set and adjust a maximum of emails in the Management
Console, but is the performance of a single Exchange server enough to
handle such bulk emailing?

Thank you in advance!

Christian

There is no limit. Exchange will accept the emails from Oracle in a
stream and then process them outbound in line with what limits you've
set on concurrent messages. Those settings are set to allow you to
control your organizational bandwidth and not have it swamped. It's
not there because Exchange can't cope - it can cope with whatever you
throw at it.

Be aware that your sending IPs might get tagged as spam-generating if 
you send mass mailings like this...

Thank you for your answers.
I'm sending the emails one by one (batch-driven), because every email
will have a different body. That's why I wanted to be sure that my
Exchange server won't crash, or "terminates unexpectedly" when it
receives that many e-mails at once.
Therefore I don't think the emails will be recognized as spam, but
nevertheless I will do a test mailing to 500 customers to make sure
they don't.

Thanks again for your fast responses.

Christian
