How to identify Outlook's "Out of office" autoreply? [duplicate]

This question already has answers here: Detecting Outlook autoreply/out-of-office emails (7 answers) Closed 6 years ago.

I'm working on a mail server that receives messages from users. I want to be able to filter Outlook's "Out of office" autoreply messages. It seems that there's no special header in those messages, so it seems that the only option is to identify them by the subject line (they start with "Out of office AutoReply").

But identifying using the subject line has it's issues too, for example -- what if the users has a different locale and the text will be in a different language?

Has anyone tackled this before a开发者_运维技巧nd has a better way to identify those messages? (or the list of translations :))

I believe JAMES has a method for identifying out of office replies. I used to work for a small ESP and that's what we used to send email and parse responses we'd get.

I know it's a bit late to reply to this but Outlook now has a rule condition called "is an automatic reply" which can be used to filter out Out of Office replies
