Recently, I discovered a small chicken named RackNerd on his rack. The upstream is ccs, but the allocated IP is 192.227.227.65, which is very beautiful!
Fortunately, my email system was recently shut down, causing many subdomains to fail to forward emails to the main mailbox. I intend to set up an email server using this IP and ask for advice from anyone who knows about it. Does the c segment have any restrictions on port 25? |
