Absolutely possible but its a battlefield on the Internet so you have to understand the players. Two things I haven't seen mentioned in all the excellent advice:
1) Does your ISP let you send email? Some ISP's will not allow any outbound traffic to port 25 from a non "business" port. They force their users to send their email to their server, and then they forward it on to the Internet.
They do this with nominally good intentions (it is easier to control spam generated from their networks), but they also are financially motivated to do so.
2) Don't try to send mail from a dynamic IP address, you should have (and would probably pay extra for) a fixed static IP address (V4 and V6).
Dynamic IPs have two problems, one they change and mail receivers don't like that. Two, they carry with them the abuses people who had the IP address before committed. So your email may get delivered one day, and then poof you renew the lease on your IP and get one that is on a black list somewhere.
That's an understatement. Reading Hotmail's policy, I saw a blanket ban on dynamic IP address. Your mail won't even attain the spam box of your recipient. It will bounce right away. Other big providers probably do the same.
In many cases to successfully sending a mail from a dynamic IP is flat out impossible.
