    I use smtp.yandex.com port 587.

    I use SPF like this -> v=spf1 ip4:103.153.3.19 include:spf.yandex.net ~all
    I’ve used the right username and password, I tried logging in on Yandex and was able to log in. So username and password are not a problem.

    The result:
    —
    220-idn12.dewabiz.com ESMTP Exim 4.93 # 2 Tue, 09 Mar 2021 21:20:35 +0700

    535 Incorrect authentication data

    I am confused where it went wrong?
