From: Jim Behning SBS MVP on 28 Apr 2010 21:08 The pop collector has no configurable settings like that. You could try PopBeamer which in days of old had some nice real time logging.

From: SuperGumby [SBS MVP] on 30 Apr 2010 02:34 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/2009/07/01/sbs-2008-introducing-the-pop3-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? http://blogs.technet.com/sbs/archive/2008/10/28/how-do-i-change-message-size-limits-in-exchange-2007.aspx Changing Pop3 Connector message size in Small Business Server 2008 http://andrius.kozeniauskas.com/blog/2009/04/26/changing-pop3-connector-message-size-in-small-business-server-2008/ Hope this helps.
