What are spamrats?

Question

Email

Good afternoon.
Has anyone experienced spamrats? At the provider, they blacklisted the entire subnet and, accordingly, letters from on do not go away. The provider constantly writes them a letter, but they do not answer. It is also not known why they contribute and how to leave their base.

Answer 1

Judging by the name RATS-Dyna, it’s something dynamic, so your pr most likely doesn’t monitor its clients well (clients are broken, simple passwords) and now spam is pouring out of their network, and not when they remove you from the list until the pr is taken by the head.
In your case, you can buy a VPS, raise a vpn there, which thread to the office, throw the necessary ports 25, 110, etc. to your server, change the MX records to VPS and that's it. as if they will always leave from another IP, they will contact the VPS, it will forward the ports to your mail.
