Sending mail(), it turned out that for several days and more than 5 tons of letters, how to cancel?

Question

Email

I sent errors to my mail via mail () and still made a mistake, I didn’t see it right away, I went away for half an hour, as a result, thousands of requests went through, which accordingly sent a bunch of letters, for the third day now it has been sending batches of 300-500 letters in half a day, I see that the letters are old, sent at that moment ... Is it possible to somehow cancel this process? Yandex mail, sending to spam is not an option, you just need to cancel ...

Answer 1

PHP process already stopped? If not, then restart the server first. Well, after that, you can already chop off the mail server that is on the server.
