Reclassify Out of Office soft bounce replies

Reclassify Out of Office soft bounce replies

Marketo can report a high number of soft bounces in Smart Lists that go onto Open/Click emails and don't show in the Email Performance Report.

The majority of these are returned with the reason '550 [internal] [oob] The message is an auto-reply/vacation mail.'
Marketo currently interprets this return code as a soft bounce action and I would like to see this reclassified to not be marked as such.

For some reason, this code didn't exist in two different Marketo instances prior to August 2019. Since that time, we've received thousands. Complicating the issue is a bounce management campaign, calling for all contacts with 3 soft bounces in 90 days to be marked email invalid. As a result of this ooo classification, we've been inadvertently marking contacts Email Invalid for 9 months. 


Very surprised that this is the only post about this issue, since that bounce management campaign was built from a popular community post - literally everyone who implemented it would have this issue. Granted, I've only looked in two instances but they are wholly unrelated - and have the same exact circumstances.


If you're reading this.. see how many Email Bounce Soft Details contains auto-reply/vacation results you get for before August 1, 2019. Then look for after.


Am I missing a data retention cutoff that removes those bounces? I've got countless other bounce codes from before August 1, 2019 so I really don't think that's it.
