Hi Cambizk,
Thank you for posting here.
According to you description, I understand there are lots of emails in
queue on your exchange server.
First I want to know, what kind of emails in your queue? Valid email
address, unknown recipients or NDR?
Open Exchange System Manager and SMTP Queues to open the Properties of the
queues which the messages are staying, which are in the Retry status and
whether there are lots of emails queued in that queue?
More info, refer to this article:
823489.KB.EN-US How to Use Queue Viewer to Troubleshoot Mail Flow Issues
http://support.microsoft.com/default.aspx?scid=KB;EN-US;823489
If the mail flow issue occurred by large emails, please perform the
following steps to limit the size of email.
please double check the following steps to rule out this cause:
Global setting
This setting determines the maximum size of the messages in the Exchange
organization; the messages can be incoming, outgoing, or internal.
To configure the global setting, follow these steps:
1. Start Exchange System Manager. To do this, click Start , point to
Programs , point to Microsoft Exchange , and then click System Manager .
2. Expand Global Settings .
3. Right-click Message Delivery , and then click Properties .
4. Click the Default tab to configure the global settings.
SMTP virtual server setting
This setting determines the maximum size of a message that is permitted to
pass through a virtual server. The virtual server advertises the limit by
means of the Extended Simple Mail Transfer Protocol (ESMTP) SIZE command
verb (RFC 1870).
Note The protocol size restriction is meant to reject messages on
boundaries with other e-mail systems. These restrictions are effective for
individual servers and should not be used as methods to limit the message
size in an Exchange enterprise server group. Administrators can set the
message delivery option in the global settings to limit and to control the
message size restriction across an organization that uses Exchange 2000 or
Exchange 2003.
To configure the Simple Mail Transfer Protocol (SMTP) virtual server setting
1. Click Start , point to Programs , point to Microsoft Exchange , and then
click System Manager .
2. Expand Administrative Groups , and then expand Your Administrative Group
Name , where Your Administrative Group Name is the name of your
administrative group.
3. Expand Servers , and then expand Your Server Name , where Your Server
Name is the name of your server.
4. Expand Protocols , and then expand the SMTP node.
5. Right-click SMTP Virtual Server Name , where SMTP Virtual Server Name is
the name of your SMTP virtual server, and then click Properties .
6. Click the Messages tab to set the maximum size that you want to permit.
User mailbox setting
This setting determines the maximum size of a message that users can send
or receive through their mailboxes. User mailbox settings are enforced by
the information store instead of by the message categorizer. The
information store prevents an oversized message from being sent to
Transport if the message size exceeds the user mailbox maximum message size
setting.
To configure an individual user's mailbox settings
1. Start the Active Directory Users and Computers snap-in, and then locate
the user account that you want to configure.
2. Right-click the user's account, and then click Properties .
3. Click the Exchange General tab, and then click Delivery Restrictions to
set the maximum size that you want to permit.
Based on my experience, there is no built-in feature in Exchange which can
restrict the number of SMTP sessions or bandwidth. However, you can
confirgure the a separate delivery schedule for the large messgaes in the
SMTP connector. For example, you can hold the messages larger than 2M and
deliver at a specific period.
For more informaiton, refer to the following article:
319426 How To Configure the SMTP Connector to Link to Internet Domains
http://support.microsoft.com/?id=319426
How to Configure the SMTP Connector in Exchange 200x
http://support.microsoft.com/?id=265293
In addition, you can specify the bandwidth for the SMTP protocol on the
firewall. For example, you can use the bandwidth rule in the ISA.
Hope this helps! If anything is unclear or you need further help, just post
back to let me know. Thanks and have a nice day!
