Is it possible to limit the number of mails being sent from an exchange 2007 send connector

Hi Guys.

Currently have an exchange 2007 server that uses a mail relay to send outgoing mail.
Customer has started doing bulk account emails being sent.

Issue is ISP Relay has a limit of 500 out going mails an hour or you get added to black list and have to wait 24-48 hour for removal while leaving the sendconnectoe queue trying over and over again to send getting me on the list even more.

Is there anyway i can setup the send connector so when it hits 500 emails in a hour it will pause the queue and wait an hour then resume?

i have taken steps to stop this happening but on a bad day it could happen so would like to be proactive and try and stop us getting blacklisted again.

Exchange 2007, no. You cannot limit this, but in Exchange 2010 you can limit this via throttling policy.

The main issue you should be addressing is this:

Customer has started doing bulk account emails being sent.

Not really a common place practice, mainly due to the issue you see. I would recommend having the client go out and purchase a third party application (hosted) that does bulk emails out to the internet. That limits the liability of something happen such as the issues you are experiencing.

I agree - this is really unwise.  If they need to send bulk e-mail, do so with a third party service like Constant contact or something else.  They are just asking to be blacklisted by doing this.  

That said, If you want to get them blacklisted even faster, then stop using your ISP as a relay and have Exchange send the mail directly.  That way the ISP doesn't "see" the message count.  Only the spam filtering providers do - who will then block them in days if not hours.

Are they advertisements, or something that people subscribe to? If so, you need to also make sure they are CAN-SPAM compliant. I am not 100% sure what type of emails you are sending, but to err on the side of caution as Lee said you can use a third party relay system to pass email via HTTPS to the smart host.
Ask them if it's worth getting their non-bulk messages to all the external recipients.  Because that's what they are risking.  Having had to FIGHT to get removed from blacklists on behalf of clients who MERELY had a previously used static IP assigned them and ULTIMATELY having to get the IP changed, you and your client can be the judge.  I think it's incredibly unwise to be doing what you/they are doing.  But what do I know...

No advertising, just simply invoices, remittance advise and statements

I ca see this being more of a problem in the future for small business customers who move from paper to emailed invoices to customers
What about asking the ISP to increase the outgoing limit for this purpose? If its for legitimate reasons AND the ISP is reasonable then it shouldn’t be a problem.
