Hi everyone, Our company plans to send email to our 27,000 customers. File size is 133KB. What will be the impact on Exchange 2010 Servers? Hub/Cas is configured on Load Balance between the 2 Servers. What will be the impact on our external address? We are afraid we will be tagged as spammers. Anyone can help us on this? Thanks. Regards, Jerome Pacificar

Yes, if you are sending bulk emails into web then there is possibility that you may be black listed. But if it happens if you send bulk email regulalry and don't have PTR records for your domain. To protect your server from blacklist, Please consider below points: 1: have a PTR records for your domain 2: Use spam solution in gatway for outbound email relay (exmple :Postini) 3: Suscribe RBL databse to check relaulary whether you are in the list. 4: Avoide open relay from your Email servers to internet PLease go thru below link for more information: http://firewallbarracudaspam.blogspot.com/2009/11/protect-your-domain-from-being.html Anil

Hub/Cas is configured on Load Balance between the 2 Servers. If the HT servers are sized properly, the effect won't be very great. I think it's safe to say they you're not sending all 27,000 addresses in one SMTP transaction so the categorizer isn't going to have a lot of work to so sorting addresses and bifurcating the message. You'll probably have 27,000 message in you delivery queues for as long as it takes to send the messages. If your pipes are big enough then bandwidth won't be too much of a problem. The delivery time will robably be throttled more by the number of concurrent sessions. >What will be the impact on our external address? We are afraid we will be tagged as spammers. Why? You said these are customers so, presumably, they've opted in to receive your e-mail -- right? You have an unsubscribe link or e-mail address in the messages, you've identified yourslf by placing your company name, address, phone number, and, in Europe, the business registration id into the e-mail, right? You have a privacy policy that the recipients can access, too? >Anyone can help us on this? Thanks. If you're worried about this then why not hire a 3rd-party e-mailer to do this? --- Rich Matheisen MCSE+I, Exchange MVP --- Rich Matheisen MCSE+I, Exchange MVP
