Right, so does AT&T.

I have my own domain, and how I’ve been getting this to work is via AT&T’s relay.  They require an SSL connection (port 993), require you to authenticate to use it, and finally also require you to whitelist additional email addresses you will be sending mail from (e.g. matt at zigg.com.)  But yes, I’m not delivering directly.

From there I have my home server’s Postfix set to use that as its outgoing relay, and then various devices can also speak to AT&T’s relay directly (which also works from not-home, for mobile devices.)
