While i click the email send, i have triggered the plugin with post condition and message as send,setEntity and SetStateDynamicEntity to trigger plugin to update current email sending activity date in the custom field as last activity. While i send normal mail it triggers and update the field, if i send with an attachment in email this plugin not getting triggered. even though i changed the steps from post to Pre-condition it not working. Sometimes it working automatically and sometimes it was not working.
