How to add login to Postfix server?
Hello everyone, something strange has started on my smtp server, there are a lot of similar requests, thousands of:
8217481456: to=<[email protected]>, relay=none, delay=37649, delays=37599/50/0/0, dsn=4.4.1, status=deferred (delivery temporarily suspended: connect to pkvw-mx.msg.pkvw.co.charter.net[47.43.26.7]:25: Connection refused)I do not have a login to the server, it connects automatically, what is this happening and how to counter it?
Mail is constantly different, did not give anyone access to ip, only checked for spam here:
