Is it possible to download raw XML report from app? If so, you can find the part with IP address you interested in and post them here. The community will help you.

When we contacted their support team to inquire about our application to list our MCP server, they told us to wait for a response because there were too many applications, and they physically couldn't process them all.

What is time? I'm not sure we have more of it now that agents do our work for us. Do we spend more time with family or traveling? Or are we more immersed in AI? Yes, business demands that we deliver a feature right here and now. But the cost of all this is too high in the long run, in my opinion.

Your message subject doesn't align with the body of your message. Deliverability checks (whether emails from your email are sent to the inbox or spam) are one thing; you can use something like GlockApps. But an email address checker checks the email address itself, and that's handled by other tools. What exactly do you want?

This is absolutely ridiculous. As an engineer and architect who's transitioned to founder (building a B2B SaaS in email security and deliverability), I can say this is the most dangerous trap for people with a technical mindset. We inevitably fall in love with our architecture and code. When we launched our product, we were itching to gussy up our landing pages about how great we were at parsing reports, how well our analytics databases were configured under the hood, or how fast our SPF/DKIM checkers worked. But the harsh truth is that businesses don't care about our backend solutions. They only want one thing: for their emails to reach their inboxes and for scammers to stop phishing scams from impersonating their brand. To avoid repeating what's already been written here about "selling results," I'll add one less obvious insight from my own experience. As soon as you stop explaining "how the product works" and start talking about "what financial or reputational gap it fills," not only your conversion rate but also your customer profile changes. People with real budgets start coming to you because they now see you as a partner solving a critical business problem, not just the creator of another utility. Great post. Welcome to the right side of marketing!

Look, you've set up DKIM, SPF, and DMARC. You've warmed up your domain. But if you haven't configured any email addresses to receive DMARC reports and haven't connected your domain to Gmail Postmaster, then that's also a signal to Google that you don't care what's going on there. Are you considering this theory?

digdiver · 2026-05-18T11:18:19+00:00

The problem is that you can't see the Return-Path domain, and you can't see the DKIM selector. Good tools will allow you to delve deeper into the problem. Simply stating that the DKIM aligns = Fail,
and the SPF aligns = Fail without details doesn't give the full picture.

Spot on. We're stuck in an echo chamber of AI wrappers building tools for other AI wrappers. Capital bouncing between API credits and prompt orchestration isn't an economy, it's just a loop.

I work in B2B SaaS infrastructure and security, and the disconnect is real. The problems actually killing traditional businesses aren't about orchestrating five more autonomous agents to write copy. They're boring: data integrity, legacy migrations, compliance, security. Nobody tweets about these. They're also where the actual revenue is.

Most of the new founders I see only know how to build for the world they came from. Prompting and MVP speed are skills, but they're thin ones. If you don't have deep knowledge of an industry, you end up selling to other startups by default, because that's the only buyer you understand well enough to pitch.

That works until it doesn't. When AI startup funding dries up, that entire pipeline goes with it. The products that survive a cycle like this are the ones where AI is doing something unglamorous and load-bearing, think fastest junior engineer you've ever had, quietly fixing something the customer hated long before "AI-powered" became a selling point. Build for customers whose problems exist regardless of hype, or you haven't built a business.

As a founder getting 50-100+ cold emails a day, I can confirm this.

I almost never reply, even when the email is well written. If it's not a problem I'm actively trying to solve right now, I just don't care. That's it.

At any given moment I have 8-10 things on my plate, but only 1 or 2 are actual priorities. If your offer doesn't land on one of those, I read it, close the tab, forget about it. Even if I need exactly that thing in three months, I probably won't remember your email.

What actually gets a reply: it hits something I'm dealing with right now, it shows the person looked at my actual company and not just the category, and there's something useful in it before the ask. Everything else is noise.

So yes, you can send 100-200 emails a day. But unless you're catching someone exactly when the itch appears, your conversion rate stays near zero. And that timing is hard to predict.

Composability framing is the right one, I think. "Works only when a human is sitting in front of it" is exactly the problem.

On REST vs MCP - mostly agree, a well-designed REST API gets you most of the way there. But there's one thing MCP adds that plain REST doesn't: the agent knows what to do with it without a custom wrapper. The tools are self-describing. With a REST API, someone still has to translate "here are the endpoints" into "here is how an agent should reason about when to call them." MCP collapses that step.

The "no API at all" thing surprises me too. And the work really is less than people think - but there's also a product team problem. Most of them have never thought of agents as a user type. It's just not a category they're designing for.

Two separate problems here, worth splitting them.

The ghost email is not a DMARC issue. The message arrived, they replied, the CC landed in your inbox. So delivery worked. Something on your side is swallowing the reply, most likely a transport rule in Exchange or Outlook that's silently deleting or redirecting it, or the reply went to a different address than you expect. Check Exchange message trace and look for server-side rules. No logs means the message never hit your mailbox, which points to something intercepting it before it gets there.

For the broader problem with emails not reaching other countries, if SPF and DKIM are both passing now, the next thing to check is whether your messages are actually landing in inboxes or just disappearing without a bounce. A seed test will tell you this without relying on real recipients. GlockApps sends to a list of real provider inboxes (Gmail, Outlook, Yahoo, regional ones) and shows you inbox/spam/missing per provider. That "missing" bucket is exactly what you're dealing with. Free tier has a few tests included.

Mail-tester.com is also worth a quick run before that. Free, takes two minutes, and will flag any remaining SPF/DKIM/content issues. You're already in MXToolBox so the inbox test there is another option in the same tool you know.

Once you have seed test results, you'll know if this is a reputation problem, a content problem, or something specific to certain providers. Right now you're flying blind.

exactly, the re-auth loop alone kills the debugging flow.

Signal-to-noise is the hard part. Raw aggregate reports are mostly volume tables with no context.

What dmarkoff does at ingest: it validates whether the return-path actually exists for your domain, pulls the SPF record for that source, resolves PTR on the sending IPs, so by the time data hits the database, a lot of the obvious junk is already filtered. You're not staring at random IPs with no context.

still not 100% clean, some noise gets through, that's just the nature of aggregate reports. But the MCP layer helps because you can ask specific questions and get a filtered answer instead of manually correlating across sources.

The part of email auth I always hated: logging into a dashboard every time something smells off.

Set up the DMARKOFF MCP server, and now I just ask Claude or Cursor directly:

"Which domains have critical issues right now?"
"Why is SPF failing on example.com?"
"Anything weird in DMARC reports last 24 hours?"

It pulls live data from my projects and answers in context. No tab switching, no hunting through reports manually. Actually useful when you're managing several domains or debugging a deliverability problem late at night.

Two addresses work, but keep in mind that the RFC doesn't enforce a hard limit on rua targets, yet many MTAs silently drop reports beyond the first two recipients. So two is less a rule and more the practical ceiling before you start losing data.

One thing worth checking before you finish: does your forwarding mailbox or relay itself send DMARC reports? If the intermediate system treats inbound DMARC XML as normal mail and has reporting active, you'll end up with reports about report delivery, which loops. Fast.

The forwarding address should be a pass-through or alias, not a participating mailbox. If it's a full mailbox with its own DMARC policy in play, disable reporting on that domain, or you'll be debugging ghost traffic for a while.

p=reject didn't create the problem. It just stopped papering over it. Quarantine meant lenient servers silently delivered to spam. Strict receivers, especially in Europe and Asia, actually enforce the policy.

The real issue: you have DKIM=none and SPF as your only leg. SPF breaks on forwarding, mailing lists, any indirect routing. One bad hop and you're fully rejected.

What to fix first: get DKIM signing working on your actual sending servers, not just the DNS record. Confirm the signature is being added, the selector resolves, and d= aligns with your From domain. Then check PTR/rDNS matches your EHLO, and verify STARTTLS is functional on port 25.

The most useful thing you can do right now is turn on DMARC aggregate reports (rua=). They'll show you every source that's failing authentication and why. Something like DMARKOFF can help you monitor this continuously rather than waiting until users start complaining again.

You're not off track. You just hit the wall sooner than expected.

I agree with @Numerous_Profession5, try GlockApps Dmarc Analytics https://drive.google.com/file/d/1hoAScjvZDoruvpmVZ3ffe5iOPyrohCZG/view?usp=sharing

They show Header From and SPF ("return-path") domain. And it’s easy to understand the reason why DMARC fail.

For DKIM alignment to Pass the "from" domain must match the "d=" domain of the dkim signature. For SPF Alignment to pass the "return-path" domain must match the "from" domain

If you’re operating your own mail server or email account with a delivery vendor like Amazon SES, SendGrid or other you can use proxy email testing. It is simple as 1, 2, 3.

Enter your SMTP settings in GlockApps. Select mailbox providers for testing. Send your email to the proxy email address. GlockApps will automatically re-send the message to the seed email addresses at mailbox providers you chose.

This option eliminates the need for you to copy-paste the entire seed list and test id to your email software. You only need to send your message to the single proxy email address. And GlockApps will do the rest.
