Zoho CEO here. Our domain was abruptly blocked by our registrar this morning. Our NOC team and myself tried to get in touch with them and they tell us "Contact our legal". Even I could not get in touch with anyone beyond their phone operator. The domain was restored, but as DNS takes time to restore, we are still facing issues. They later claimed there were abuse complaints about Zoho.com emails (which is our persona…

I find that abusive.

Yes making sure that people are aware that their personal information is at risk from a company that touts itself as a bastion of privacy. Very abusive. Sorry you feel that way? Downvote me and move along then. We'll let up/downvotes play out and the community can decide just like it's designed to.

If you’re providing email service, you should be actively monitoring public blacklists, not waiting for your registrar or hosting company to notify you. Even if your domain isn’t banned, your users’ emails may be bounced by other servers. That you don’t seem to know any of this means you aren’t employing the right people.

I'm pretty sure you're over inferring stuff from that post. It's not credible that 20+ years old company serving email for millions of users wouldn't know the most basic stuff about running an email server, don't you think?

If you’d like to use a strong captcha approach without using a competitor you might want to check out http://funcaptcha.com (I have no affiliation, have heard good things and been presented it on a couple of sites)

The "Book Demo" button and "read white paper" button seem to be broken, which does not inspire much confidence. The first button just takes me to the bottom of the page while the second button does nothing. Not sure if this is the same, but I once came across a website with a captcha where you had to rotate a dog so it stood upright, but it was lagging so bad that it would skip several frames, making it impossible to…

It sounds like the spammers found a way to automatically create new @zoho.com email accounts, and the single way to stop them might be using a CAPTCHA service from the direct competitor, Google. At least that was the unfortunate case for the privacy focused German email provider Mailbox.org[1]: > We recently detected activities on our servers where bot nets were used to create hundreds of thousands of e-mail accounts…
