Re: Microsoft missing public DNS TXT entry for DKIM records (msn.com)

It appears that Adam Brenner via NANOG <adam@aeb.io> said:

mail server. Our mail server checks if DKIM email headers are present and if they are, tries to validate them. If the check fails, we reject the message.

MSN's setup is broken but let me strongly reiterate the advice DON'T DO THAT. If a DKIM signature isn't valid, you ignore it. If you do anything else, as you have just discovered, you will be sorry. R's, John
