How big of a limit do you want to change it to? Keep in mind, as Larry
said, Exchange is a poor file transfer system. The Transport service
will hang with large attachments effectively disabling all emails.

I had to mention that. That said, here are the locations:
=============================================
1. Organization, Hub, Send Connectors Tab, "Maximum Message Size
(KB)."
2. Organization, Hub, Global Tab, Transport Settings Property,
"Maximum Receive Size (KB) and Maximum Send Size (KB)."
3. Server Configuration, Select Server Name at the top, Receive
Connector tab below, In the Connector called "Default ServerName"
Properties, Maximum Message Size (KB). If any clients are using POP3
or IMAP4, also change it in the "Client ServerName" Connector.
=============================================


If you have a third party SMTP gateway or Edge, it has to be changed
there as well.

Hi Stuart:

How large is that attachment? As SG has pointed out in other threads on
this subject, attachments can grow to 125% or so during the download process.

Could also be the message and not the attachment. Pop3 collector for SBS
is problematic at best. Several posts in this or the 08 group about this
recently.

My advice is to open that mailbox with web mail and save the attachment to
your local drive. Then, if possible delete the attachement and see if the
mail comes down sans attachment. If not, read it with web mail then delete
it.

I am not going to repeat all the teeth gnashing and hand wringing that goes
on about this, but you can search for it in the SBS groups.

Next advice, but you already know this, is to use SMTP for mail as the mail
gods intended. <g> redundancy and so on can easily be implimented for less
than the cost of messing with pop3.

I'd have to point out that there's a bit of 'license in interpretation'
being taken there. Attachments don't cause growth in size during download.

Depending on email client and the servers involved. When you attach a 30MB
file to an email message the attachment is subject to encoding as email
systems ONLY pass 'plain text'. The encoding makes the whole message size

>30MB and due to inefficincies in MIME highly compressed files can grow

quite dramatically. 7bit MIME is even worse than 8bit. Hence, depending on
mail system, a message with a 30MB attachment _may_ break a 50MB limit.
Something with a 50MB attachment may blow out to 80MB easily.

AFAIK the actual number being thrown about in the coversation LS is
referring to was 133%, I suggest even greater. Moving files of this size
over email is sheer stupidity. Moving it through POP is simply asking for
trouble. However...

http://blogs.technet.com/sbs/archive...connector.aspx
By default, messages exceeding 10 MB will not be downloaded by the POP3
Connector. An event will be logged in both the pop3service.log (if verbose
logging is enabled or if you used "Retrieve Now") and the Operational log in
Event Viewer. The POP3 Connector is not hard coded with this limit, it
reads this directly from the max message size setting on the Windows SBS Fax
Sharepoint Receive connector. You can increase this as needed, however you
must make sure that the global and mailbox size limits in Exchange 2007 are
set properly as well. If not, the POP3 Connector will remove the message
from the POP3 server, but Exchange will reject it.

Hello Stuart,

Thanks for your post and others' good input.

As far as I know, SBS 2008 includes a brand new version of the POP3 connector and it performs the following steps during its mail-flow lifecycle:

a. A connection is established to external POP3 Server.
b. Each user's mailbox is accessed with the credentials stored in the POP3 Connector's configuration.
c. Email is downloaded and deleted from the source mailbox and then submitted directly to the Exchange Transport service via SMTP.

The maximum message size that can be processed by SMTP is 10 GB. Because of this, the POP3 Connector does not attempt to retrieve messages that exceed 10 GB in
size. Windows SBS 2008 does not log an event if this occurs.

Moreover, as we know the Exchange 2007 server Receive Connector will take effect automatically according to the IP address range. That is to say, there should be ONLY
ONE receive connector that really applies to the POP3 emails size restriction. I wonder it is the "Windows SBS Fax Sharepoint Receive SERVER-NAME".

How Do I Change Message Size Limits in Exchange 2007?
