### Fix
Tweak the [<b>postgres-app/sample-configuration/mailetcontainer.xml</b>
](https://github.com/Arsnael/james-project/blob/postgresql-merge/server/apps/postgres-app/sample-configuration/mailetcontainer.xml)
file:
- Add these mailets under the *"transport"* processor.
```xml
<mailet match="RecipientIsLocal"
class="org.apache.james.jmap.mailet.filter.JMAPFiltering">
<onMailetException>ignore</onMailetException>
</mailet>
<mailet match="RecipientIsLocal" class="VacationMailet">
<onMailetException>ignore</onMailetException>
</mailet>
```
- (Is this required?) Add this matcher under the
*"transport.relay-allowed"* matcher
```xml
<matcher match="org.apache.james.jmap.mailet.SentByJmap"/>
```
The JMAP backend has been functioning smoothly after these additions, but is
there anything else that needs changing?
