No, the chat is not working. Tell me plz.
that's all that was sent from 1box
noreply@univer.ua to
varnava.a@gmail.comand the letter did not come
I see the following problem:
Client with IP address 185.156.202.90 has no reverse DNS entry, connection rejected before SMTP greeting
it seems that the letter is not sent from Microsoft, but directly from this server...
Message from IP address 185.156.202.90, sender <univer1bapp@new-univer.1b.app> rejected: sender domain does not exist
