You have to remove distinct="true" form your fetchxml and then it shall work.
Try below fetchxml
<fetch version="1.0" output-format="xml-platform" mapping="logical" >
<entity name="email" >
<attribute name="modifiedon" />
<attribute name="sender" />
<order attribute="modifiedon" descending="false" />
<filter>
<condition attribute="modifiedon" operator="on-or-after" value="2020-03-25" />
</filter>
<link-entity name="activitymimeattachment" from="objectid" to="activityid" link-type="inner" alias="ak" >
<attribute name="filename" />
<attribute name="body" />
</link-entity>
</entity>
</fetch>
