Hotmail does not work (Recipients belong to multiple regions) #1334

Closed yaiqsa closed 10 months ago

yaiqsa commented 11 months ago

Email Provider

hotmail.nl, hotmail.com

Version of check-if-email-exists (if running it yourself)

0.9.1

What happened?

I executed this from the server that I usually send mail from: (I replaced my actual mailing domain etc. with mocks in the command & logs)

RUST_LOG=debug ./check_if_email_exists --from-email test@domain.tld --hello-name domain.tdl user@hotmail.nl

This should return a "safe", because the hotmail address I used exists.

The thing is; when I manually open a telnet session to the outlook mailserver, and I pass the actual mail address, it is accepted. When I emulate Reacher and first try a random receiver address, and then pass my actual mail address in the same SMTP session, I get the same Recipients belong to multiple regions error. So I think the problem is that Reacher's way of checking the address just doesn't work properly for outlook. Maybe it should use two separate sessions?

Seems it happens with all *mail.protection.outlook.com related domains.

I got same results with valid and invalid (no existing email) in our tests

In https://github.com/reacherhq/check-if-email-exists/pull/1336, I removed the first random email check for hotmail (and gmail and yahoo). This should fix this issue, I'll tag 0.9.1 in the coming days.

Edit: v0.9.1 tagged.
