Ax2009 Exchange and port 25

Hi All,

we want to do an auto batch mailing from axapta. We dont gonna use a outlook client for this.

But because of security reasons we have blocked port 25 in the ex change environment,. (blacklisting etc)

How can we set ax (2009) so that we can use the auto batch script?

Can we set it to another port and fill in credentials then or must we use it anonymous
