i hope you are well and safe.
i come to you because my company was victim of email spoofing.
mad people send emails with real address with our @domain.tlg to internal users and to some Customers.
in fact, Customers received some emails “from” my email address but off course from external servers (not mine)
with current settings set on MIAB : _dmarc.domain.tld TXT v=DMARC1; p=quarantine
emails that are not coming from my email server are moved to spam.
my wish is those kind of email are totaly rejected.
if they do not come from my server, they absolutely do not need to go to spam but garbage directly
i would like to update : _dmarc.domain.tld TXT v=DMARC1; p=reject.
how to proceed on MIAB please ?
Internal DNS are used (so those set by MIAB).
many thanks in advance for your support.
long life to MIAB, i used it since 3 years now, zero issue met since
updated every time a new version is published
it is a pleasure.
