Email limits

I have an SBS 2003 R2 server and the limit for sending and receiving email
is set at the default level of 10,240KB. I have noticed that some users
that do not have a custom limit set have, for example, emails from 11MB to
16MB in their accounts. Is there another place I need to adjust the global
limits for email?

Thanks,

John

Thanks for the response. After further investigation, I have found people
with emails up to 70MB in their account. Clearly, the defaults of 10,240KB
for sending and receiving email do not work.

Ah, I didn't think of that.

There's also the SMTP connector and the SMTP virtual server. I'm surprised
at John's issue because I thought the lowest limit setting trumped
everything, except an individual limit set in the user's mailbox. By
default, there's the 10 mb setting in global properties, and nothing is set
in the SMTP connector or virtual server. Regardless, I think all the
answers are in this KB:

How to set size limits for messages in Exchange Server
http://support.microsoft.com/kb/322679

BTW, I'm at least 99.9% sure the global limit applies to internal messages
as well as those to or from the Internet.

and that KB doesn't mention it but isn't one of the settings (most probably
'connector') default 'not limited' actually a default of 10MB? To actually
increase the size above default you must select to limit and then set a
higher value.

Why anyone wants to do something as stupid as sending 10MB emails is beyond
me though.

Hi John,

Thanks for your post and others' input.

Size limits for messages depend on various settings. Settings can vary across users. You can customize the settings for the Exchange 2003 organization, a specific
connector, a specific virtual server, and an individual user. All Internet e-mail messages use the global setting for limits on sending and on receiving.

If you(external user) can receive the mail with 11MB size, it indicates the Global size limitation is large than 11MB. Because all Internet e-mail messages use the global setting
for limits on sending and on receiving. The message categorizer evaluates the sender's sending limit and the recipient's receiving limit. However, you still need to check
other size limitation for internal traffic, e.g. checking the SMTP virtual server size limit and User's personal size limit via AD Users and Computer console as user settings
overrides the global setting.

For more information, please see the article Dave recommended:

How to set size limits for messages in Exchange Server
http://support.microsoft.com/kb/322679/en-us
Note: Please understand the two examples at the end of the article.

Hope this helps.

Back when we were using an external pop3/smtp server at our web server, our
graphics production guy--the only one using a Mac, naturally, would
routinely use email to get either graphics or finished products as PDF's
back and forth to the users.

These were often many megabytes, but with broadband, nobody really noticed
except when they never arrived because they were filtered off--I think the
software on the webserver shoved the oversize messages to an admin mailbox
which we weren't in the habit of checking...

To the users, it just seemed natural--easier than putting the stuff in some
fileserver location and communicating that to the other party involved.
Nobody considered the wear and tear of all those bytes on the poor copper
wires....

It doesn't affect copper, rather your database size, and depending on the
speed of your link (internet) inbound and outbound large emails will cause a
performance drag on the machine, since you are literally trying to use it as
a file transfer machine (like FTP).

Actually they don't get filtered off to some admin mailbox, they simply get
rejected and never arrive. It's part of the SMTP connection session process.

Hi Robbin,

That's a lot of info to digest. If I go into the Delivery Restrictions for
a specific user and set their send and receive size to 4MB for instance,
will that override any other settings in Exchange?

Thanks again,

John
