why doesn't any ports actually open except for 80,22, 53 and 443?

i have created a firewall and i want the below opened and it doesnt work?

Furthermore the ticket support is not helpful either?

PORT E SERVICE 143/tcp imap 587/tcp submission 993/tcp imaps 995/tcp pop3s 3306/tcp mysql 4190/tcp sieve 4949/tcp munin 25/tcp smtp

How can i open the above ports?

deleting the firewall does nothing either

Do you have any services running on those ports on your droplet?

To check that use the netstat -plant command.
