Messaging Gateway

Hi all!

Just had a request from a customer who updates his mail server every Friday at which point approximately 25000 emails are received to it in one hit. Would Brightmail Gateway be able to handle this kind of sudden heavy load . Has anyone else had experience of receiving large volumes of emails in one go?

Cheers!

Absolutely. Here is the thing though, while his mail server is offline, the messages would queue up on the Messaging Gateway and then send to the mail server is in the same way the external mail servers would. You can limit how many message the Messaging Gateway send his mail server at once though and throttle it down a bit.

Agree with TSE-JDavis.   When we've had issue that stopped SBG from sending, we have had queues over 4-5,000 messages clear in a couple of minutes.

Depending on the flow direction you will want to look at the Scanner's  # of connections per IP and # of messages per connection settings.  If this is outbound, you need to be careful that you don't cause the external recipients to flag you high flow rates as spam.  I know Yahoo.com does this if you deliver at to high a rate. 

Its under the Advanced tab,

Maximum number of connections:

Maximum number of connections from a single IP address: (you might want this lower on the i/f getting the 25000 messages dumped on it.

Maximum number of messages per session:
