Applies To: Microsoft Dynamics AX 2012 R3, Microsoft Dynamics AX 2012 R2, Microsoft Dynamics AX 2012 Feature Pack, Microsoft Dynamics AX 2012

Click System administration > Setup > System > E-mail parameters.

Use this form to set up Simple Mail Transfer Protocol (SMTP) to send e-mail, similar to the way used by Microsoft Outlook and Microsoft Outlook Express. These parameters are required to generate e-mail messages for users.

In addition to the protocol setup, you can specify a set of limitations to e-mail messages sent.

The following table provides descriptions for the controls in this form.




Outgoing mail server

Specify the name of the outgoing SMTP mail server. This information is provided by the system administrator or your Internet Service Provider (ISP).

Local computer name

Type the local computer's name or Internet Protocol (IP) address.

SMTP port number

Specify the port number to be used with the SMTP server (the default is 25). This port number should not be changed unless the system is specifically set up to use an alternate port.

User name

Type a valid user name (if the SMTP server requires authentication).


Type a valid password (if the SMTP server requires authentication). If you access the SMTP server through more than one client, the password must be entered from each client.


Select this check box to enable Windows NTLM authentication. You must select this option to send an e-mail message by means of an SMTP server that is configured to use Windows authentication.

Attachment size

Specify a system-wide size limit for e-mail attachments. The maximum buffer size, defined by the maxbuffersize registry key, also limits the acceptable attachment size. If the size that you define here exceeds the maximum buffer size, the maximum buffer size limit will apply.


When setting the acceptable size of e-mail attachments, consider the fact that any large file passed to the Simple Mail Transfer Protocol (SMTP) may slow the application and may cause denial of service to other users.

Allow embedded data and attached files from

Specify a system location for e-mail attachments and embedded e-mail data. Attachments from other locations than the one that is specified are restricted. The location should be on the server or, alternately, on a share.
