DMARC failures

    Question

  • We have recently setup DMARC record for our domain in audit mode. We have been getting DMARC Failure reports from Linkedin.com. The messages that getting failure reports are  "out of office" messages . 

    I this because of reply address being null  smtp.mailfrom=""  

    Is there anything we can do to fix this.

    Nope! Other than not allowing OOFs to external perhaps?

  • Agree with Andy, this is a "by design" issue and nothing much to do about it. You might need to create separate rule for it on your appliance used.

  • Thanks Andy

    So you are saying this is the default behaviour with DMARC and there is nothing we can do other then stopping external out-of-office messages .

    If the alignment fails between the FROM and MAIL FROM: DMARC fails, so that's what you are seeing for those OOFs.
