#102Why this is not a library instead of hosted api? Why do we need to run this as a service? does it come with its own DB & all?

Not really: but majority of spammers think that they are doing marketing.
I've never once received a "marketing email" that wasn't spam.
That’s you (and the large part of HN who doesn’t know anything about normal users). When GDPR came into effect, we even had people write us that they were annoyed having to reconfirm, as obviously they still wanted our newsletter.

This isn’t just good against spam. If there’s a data breach on the site, it’s another layer of insulation against you and other accounts you own. It’s close to the equivalent of Apple allowing you to sign up to services using one of their anonymous emails — there’s clearly demand for people to want to keep their emails from being thrown around everywhere.
Wouldn't someone be able to reverse engineer the pattern? I assume everyone is doing some variation of so someone can try to figure out your other email addresses for other sites. Although I don't know if that's worth the time investment.
For the catch all email setups yes. Not with the way apple does it. They have specific mappings setup so you have no way of finding other addresses of the user since every apple user is behind the same domain and the emails are long/random.

#105Could someone spell out a use case for this? One that comes to mind would be validating that a mailing list doesn't have any outdated email addresses in it, but couldn't that be determined by just checking for a bounce when a message is sent to it? I tried to sign up for SiriusXM the other day, and though I could create an account with my .pro email address, I couldn't actually sign up for service with that same addr…
A non-marketing example:
We were onboarding a large new client to our SAAS product. This process involved creating accounts for all of their employees (tens of thousands) and sending emails with an activation link. (Where they'd be able to set up their password.)
Our system sends these emails in batches, and as soon as the first batch went out we got an alert from our monitoring system that our bounce rate was surging - high enough to risk a sending pause from Amazon SES. We stopped sending and investigated the issue, and it turned out that the email list we were given was a mess - it included all current employees, but also a huge number of former ones. Just under 1/10th of the emails in our first batch were invalid.
We asked the client to give us a better list, but due to internal issues they couldn't get that to us any time soon. Meanwhile they were breathing down our necks to get these emails out ASAP, and they were a large enough client that our management wanted to keep them happy, so we tried out one of these email validation services. Unfortunately, it didn't work. It turns out that this technique doesn't work for all mail servers. It was reporting every email as valid, even ones we knew were invalid since they'd already hard bounced.
(Edit: thinking back - this was several years ago - I think it wasn't saying that they were valid emails, just that it couldn't tell whether they were valid or not - the service was able to detect that the server wasn't rejecting non-existent addresses.)
We ended up unpausing the emails and just hoping for the best. Ended up with something like an 8% bounce rate that eventually fell off our record as our normal sending patterns resumed. Amazon's guidelines say they might cut you off when you hit 10%, so we cut it pretty close.

#106I feel like this will get your IP on block lists really quickly.

#107Disclaimer: IANAL. This is a particularly interesting use of AGPL because it appears to contain a RESTful HTTP server built-in. To my knowledge, with the way AGPL works, there are some interesting wrinkles: - It is only intended to “trigger” when distribution occurs under some legal copyright law definition of “distribution.” - It allows commercial use of unmodified and modified instances of the licensed code, as lon…
FYI: the additional requirements of the AGPL over the GPL trigger on modification not on distribution:

It seems like the most practical solution to that should be calling AWS, explaining it for 5 min, and getting an exception. Is that kind of reasonable solution no longer possible with the cloud providers being so huge?

I'd hope you'd at least be able to explain the situation to your account manager and get an exception(maybe for that single companies domain?), but I've never used AWS so I wouldn't know if thats possible.

I would love to clean up my addressbook removing no longer valid email addresses for contacts.
