msg id from another servicenow messing with my inbound actions

[Kristin Acree]

I received an email from another ServiceNow system. They have a message ID on their email. And it found an unrelated Incident that it attached itself to. 

How can i ignore other ServiceNow's MSG ids? and only pay attention to mine.

Hi @Kristin Acree 

is it PDI or client? you can create an inbound action, something like "if email is <that mail>", do nothing. 

Eventually "stop processing: true"

@Kristin Acree oooooooor create a user account, assign it that email address and deactivate that user, it shall be hopefully enough to block it

i want the emails that are coming in, i want an inbound action to run. Just their MSG ID, is attaching to another record, and not running the inbound action properly b/c of that. 

i was hoping i could find how its running, and tell it to ignore if coming from a specific sender.

• You have activated the Random Watermark Support plugin.
• The sys_properties record glide.email.watermark.parse_restrictive value is true
• The emails watermarks are not recognized, and they look like Ref:MSG0000001 (instead of Ref:MSG000001_asdrewtwer)

We are an older instance, got servicenow before Jakarta so..... the plugin wasnt auto turned on for us.

Starting with the Jakarta release, the system automatically generates randomized watermarks for notification emails in base systems. The random 20-character string reduces the possibility of a watermark being guessed or coincidentally matching the watermark of an email from another instance.

Note: If you are upgrading from a release before Jakarta, random watermark support is optional and requires the Random Watermark Support plugin to be activated.
