@sru: Yes, that submission line is generally followed by a couple more specifying SSL and authentication.

Butbutbut doesn't :587's RFC *REQUIRE* authentication (i.e. it should not allow delivery even to local users without auth)? It shouldn't be a plain "copy" of :25.

And if your home machine is running linux, you can test your mail server's new config by running the 'swaks' command:

swaks --from me@example.tld --to my-offsite-box@example2.tld --server my-mail-server.example.tld -a -au my-username -ap my-password -tls --port 587

Yeah, the mix of single-dash and multiple-dash parameters is intentional. Swaks has funny arguments.

If you have never playes with swaks, learn it. Especially if you're a mail admin. Awesome tool.

@Trashman - Thanks for spotting the error! I've corrected it in the post.

I think you mean: /etc/postfix/master.cf (not main.cf)
