Good day guys.
My MX and A configurated in your base but they are not working .What is a problem another WEBs working but this no
host mxs.mail.ru [188.8.131.52]
SMTP error from remote mail server after end of data:
550 non-local sender verification failed
Reporting-MTA: dns; homemilfs.xyz
You’ll need to check with the owner of the mail server. Based on the error message the specified host mxs.mail.ru has rejected mail because non-local sender verification failed. There is no actual standard for that… so perhaps they can tell you what they are checking.
