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.

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.

Thanks in advance :-)

>I've seen a 1GB message crash an Ex2003 server. It's not pretty :)

I had an astute user interested in doing non paid work from home by means of
reading help files take the entire autocad dir under program files and drag into
an email. There were a few log files made for a "short" interval while that 
server
fsck'ed off into oblivion:)

I've seen this discussed here before, I wonder if that behavior has changed wrt
OL and exchange finally?

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.

RE: Theoretical maximum message size in E2k3?

2011-09-30 Thread Michael B. Smith
The technical limits are likely to be on the e2k3 server itself.

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.

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.

Thanks in advance :-)

Meant to add that my google-fI has failed me on this and i've tried reading
the e2k3 technical reference, but only came across the database size limits.
