@icloud.com ### From where did you run check-if-email-exists? OVH ### Version of check-if-email-exists (if running it yourself) d4b5ef9696a8c3ff0eaad2d3b5321437bd2a4df3 ### What happened? When I verify any emails on icloud.com, I get the two errors - 503 5.5.1 Error: send HELO/EHLO first - 5.5.1 Error: need MAIL command Even though I already explicity sent EHLO. This is also reproduced using telnet.
