Exchange Server sending limit

Posted on 2010-11-29
Last Modified: 2012-06-27
We have our Exchange 2003 message delivery defaults (under Global settings) as sending message size: no limit and receiving message size 15 MB.

On the SMTP virtual server properties we habe the limit message size to 15MB - (I'm assuming that is for sending only???)

So what is the real outgoing message limit? Does it take it from the global settings or the smtp virtual server?

Please have a read of the following for all the locaions that you can set message size limits in Exchange 2003:

Outgoing message size limits are set on the global Settings> Message Delivery Properties as per the link above.

If you want a size limit for incoming and outgoing - make sure all the limits are set to the required size, otherwise one will trip you up.

I read that article before I posted the question but it doesnt answer my question specifically.
I need to know what my true outgoing size limit is according to my Exchange settings.

the global settings are for within the Exchange organization only (which I'm not interested in) and the smtp virutal server is both send/receive for all emails going through the smtp virtual server to our barracuda. So since all our email comes and goes thru the barracuda then the send limit is set on smtp virtual server which is 15mb. I think i just answered my own question.

If the SMTP Virtual Server is set to 15Mb on the "Limit Message Size To" field - then this is your send limit. If you click on the Help button - it gives the game away for you:

Use this option to prevent users from sending very large e-mail messages.  If a user tries to send an e-mail message that is larger than the maximum message size specified, it will be returned to the sender as undeliverable."

Either way - the smaller limit will be applied.
