Remember, Exchange 2003 is a 32-bit application and is limited to 4GB RAM and the store consumes most of the RAM on that server. You can have a look at the Technical Reference Guide for the transport layout for the WHY, but you'll see that any message going through an Exchange 2003 server requires about 2.5 times the message size in RAM and about 4 times the size on disk (some temporary, some in the System Attendant mailbox). The effective limit is going to be different on just about every server. There is no theoretical limit that I am aware of. But I've seen 150 MB messages crash Exchange 2003 servers because Exchange 2003 does not deal very well with running out of memory. These things have changed dramatically by Exchange 2010. You could use email for VLFs in Exchange 2010, but I would still say that email is the wrong way to do it. Regards, Michael B.

Does SMTP /have/ a theoretical limit on the size of a message? You'll hit technical limits (imposed by organisations/servers over which you have no control) far quicker though.

Hi folks, I've just been asked by a customer that if we remove the send/receive limits, what is the technical/theoretical maximum size of a message that can be sent? Discounting all other factors such as mailbox and storage group sizes.
