Does your email server implement?SPF, DKIM and DMARC?
Mine?
Yes, no and no.
I'm pretty sure I haven't suffered from any instances of spam runs
sent out with my domain name forged as the source address although
I am not sure I can believe that the spammers are smart enough to
have checked for the existance of SPF and decided that this would
make it not a worthwhile thing to do. I really only have it so
that if this did happen, the recipients would have an opportunity
to identify what they are receiving as forged and unauthorised.
