Our blog shares expert insights on email security, DMARC configuration, and deliverability optimization.
Forums show the same anxiety pattern: 'I want p=reject, but I'm afraid I'll block legit mail.' The rollout is mostly about gates: inventory done, alignment fixed, SPF lookup limit avoided, and then staged enforcement.
Forwarding and discussion lists are a classic DMARC pain point: SPF usually breaks, DKIM sometimes breaks, and then users blame the receiving org. We explain why this is structural, and how ARC and SRS attempt to fix it.
A recurring forum storyline: you set up an ESP, authentication tools say it's fine, yet DMARC alignment is still broken. This usually comes down to how the ESP signs DKIM (d=), whether you're using a custom sending domain, and whether you should isolate with a sending subdomain.
Forum threads keep repeating the same confusion: "SPF and DKIM pass, so why does DMARC fail?" The missing mental model is DMARC alignment. We explain aspf/adkim, organizational vs strict alignment, and why you likely rely on DKIM alignment more than you think.
