It’s reddit, you get what you get. That’s why the majority of us stopped using it.

That might not work either. If a server marks it as spam, we do something called blackholing the email, meaning we discard the email and close the connection without responding to the sending server. This is done in an effort to provide as little info as possible to a bad actor.

If you don’t send an email from a server and address deemed reputable and with a low enough spam score, you’ll be shut down by more than 95% of the mail servers out there.

There’s really not enough info here to help you. Are you looking for software? Writing it from scratch? Web tool? Bulk or not?

I don’t know how many addresses you plan on testing on any one server but we’ve been on to this trick for decades now and the firewall will block you from almost every server once you try a non-existent address a few times(for my servers, it’s 2). Many servers also report bot/spam IPs to the ISP and if you get reported enough time, your connection could get shut down.

What’s odd is that they tell you you’re banned for breaking an unnamed rule then invite you to create another account. If it were an offensive username, you’d think they would just force you to change it. What’s the point of banning an account then asking the banned member to create another account?

I would guess maybe that’s what’s causing the issue for you then. If a bunch of bots were doing something using that IP address you may have just got caught up in that. I don’t know how much help reddit’s customer service would be if if there even is an outlet to dispute it, but maybe somewhere in the notice page you’ll find a way to ask for human review.

Are you using a VPN perhaps? Maybe they corralled the accounts coming from a particular IP.

Out of curiosity, how many reddit accounts have you had and were you reprimanded on them? It looks like they’ve just sussed out your other accounts.
