Which POP-enabled email provider bans less than others?

So I am in need of thousands of email accounts. It does not really matter from which provider, as long as POP is available.

What matters is this: As we all know, Gmail and Hotmail and Yahoo might ban you if account is created in one location, then you log in through a completely different location another day or from a bad IP.

Which providers do not have this problem? Are providers like Yandex and Mail.com ignoring this stuff?

the good thing is that if you use POP access, you don't login to the accs using a browser, the ip rules are much more lenient this way or maybe even non-existent, i have a bulk hotmail checker which works via POP, i use it to check plenty of accs at once from the same ip in a blink of an eye and never had a single problem because of this
hotmail is the cheapest and you can also have 8 or 10 aliases per address (i don't remember the exact number) which makes it even more cheap
just don't login to the accs using a browser, only via POP and you'll be good
