Resolved DNS issues after domain migration to Plesk server

[Mikelug]

Server operating system version

Ubuntu 20.04

Plesk version and microupdate number

Plesk 18

Good morning, recently i change the name servers to one domain from one enterprise to my plesk server, but the MX record doesnt work. The problem is caused because that same record MX mail.------------.com was resolved by other ip and now my Plesk server try to connect to the old ip instead of connect to himself.
So, its any form of clean DNS cache?

Thanks.

A DNS update can take serveral hours to propagate. How long has it been since the new nameserver entries became active?

Good morning, sorry for the delay, the problem was generated by a firewall rule too restrictive, thanks for the answer.
