Port 25 Email Hosting
Good Morning, I am interested in hosting an email server to support a couple of applications I'm developing. I am curious if Linode is willing to open traffic to port 25? I am looking to migrate from Digital Ocean for this very reason.

I run a mail server on my Linode…and have for nearly 10 years.
Port 25 is usually used for computer-computer mail transfer. If you are going to use Gmail or some such as your server, you're going to have to use one of ports 465 (ssmtp) or 587 (submission).
See the FAQ post above about mail ports.
