Bulk email

Hey guys

We have an Exchange 2010 environment with plenty of space along with decent bandwidth. Our press department would like to send out emails to around 1800 people with 2MB attachments.

I'm concerned that this email would end up holding up things in the queue due to the large recipient number. Are you able to indicate what you would do? Would you seek an external supplier for such a thing?

Or are there ways to make use of Exchange in a way which won't affect anyone?

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Exchange transport config allow 5000 max recipients,so i don't think that it will cause an issue for exchange

I would strongly suggest that sending that many emails at a time is going to trigger just about every spam filter in the country.  Make sure that you send a copy of the email to an outside recipient not on your network and check the X-Spam level - It needs to be under 5.0

Check first and make sure that your smtp server is not on any spam lists  (I use mxtoolbox.com) to check top be sure you are not on any blacklists

Most bulk email programmes will send directly (i.e. they don't require to go though exchange) - if you really need to, you can can send via exchange, but you might be better served having a small mail engine (such as mercury, or exim on cygwin) which you can run on a workstation and handle your outbound bulk mail send for you.  That not only avoids the thoughput issue, but if you have a significant amount of bounces and/or trigger spam detection, avoids your exchange IP address being added to spam blacklists.
Creating Active Directory Users from a Text File

If your organization has a need to mass-create AD user accounts, watch this video to see how its done without the need for scripting or other unnecessary complexities.

I would also consider posting the 2M file online (Dropbox, Skydrive, etc.) and just email links to it.  That would eliminate about 3.6G of traffic from your site and also gives the recipients the option of when to download the attachment.

This assumes, of course, that the 2M file is the same for all recipients.

Which is a good point, CompProbSolv - many email systems will not accept a 2MB attachment, while a link is relatively small.
You need to very carefully check mail list and send from real attended mail account (like functional mailbox) and clean up lists accordingly
