Ports are set to allow in ufw but shows blocked

np flag

I am very new to using ubuntu, I was trying to configure my plesk email but realized I am not able to receive or send emails. I have configured the correct ports with ufw allow, but they show blocked on an online port scanner.

The ports

All these ports also are allowed in, however on the port scanner website this is what it shows for those ports, port 21 25

All the other ports such as pop3 ssl, imap ssl also show closed. I have enabled and disabled ufw to try updating it but it does not seem to work.

I sit in a Tesla and translated this thread with Ai:

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
