Hi @rich1991,
For local installations, you can use an email relay to send all emails to a service such as mailtrap which will collect all your emails in a single inbox. Optionally, you can also forward them (manual and even automated) to another email address of your choice.
What you need to do is the following.
1. Update the mta process element of your instance configuration file as follows:
<mta autoStart="true" statServerAddress="localhost:7777">
<child>
<smtp>
<IPAffinity name="default,mid.default,dev.default,test.default">
<!-- For dev instances, if you need a default IP (not recommended), use address="0.0.0.0" -->
<IP address="0.0.0.0" heloHost="<<name_of_your_computer>>" publicId="1" weight="1"/>
</IPAffinity>
</smtp>
</child>
</mta>
2. Update the mta process element's relay element in your serverConf file as:
<relay address="127.0.0.1" port="25"/>
This example assumes that the email relay used is listening on port 25.
Let me know if that helped.
