Hello list,
Should we reject failed message on DKIM validation stage, or DMARC
validation stage, or both?
Just my opinion...
I see lots (and I mean lots) of DKIM failures due to mails sent to
mailing lists that have clueless administrators.
I also see lots of DMARC failures arriving to mailboxes of people that
insist that forwards are a proper way to handle mail.
(Please, if I am wrong or otherwise forgetting the proper way to handle
the above situations give suggestions, they will be welcomed)
So, instead of a plain reject (that may have the side effect of
discarding legitimate email) I send those to a Spam folder.
Thanks.
