Are you getting lots of SPAM? Is your organization’s internet link being saturated due to tons of inbound spam and maybe outbound non-delivery notices for invalid addresses? About 3 years ago, ours was too. We also supported several domain names across multiple sites. We subscribed to Postini (now Google) services to reduce the impact on the internet connections at our sites. After implementing Postini, we saw a drop in the number of inbound messages and bounced undeliverables of over 85%.
Postini was seeing almost 9 out of every 10 messages as SPAM or bad addresses. This is a huge amount of traffic hitting the circuit(s) and not to mention the email servers and user mailboxes. Postini has saved lots of money on both communication costs and servers. I urge you to take a look at their services or other similar “cloud” services.
We recently made a change that was done at NO COST and are seeing savings in network traffic and server load. We got rid of the multiple domain names and went to a single email domain for the entir organization. Before making this change, the total number of inbound messages was about 60,000 per day. After making this change, the number was reduced to 13,000. This is a >4X reduction in inbound messages! This was done at no cost. However, it is not without risk so a lot of up-front planning and communication is needed. All employees needed to ensure that their contacts knew their new addresses. An autoreply was also implemented on the edge email gateway to reply to all messages addressed to the old domains.
Savings can come but there are risks. All interested parties need to be kept informed during the changes. Think about what changes can be done in your environment to save costs. It may not be easy, but sometimes can be very effective.
Thanks for reading & let’s continue to be good network citizens.
