Briefly (well more like 3-4 years) had a free dyndns account and ran my own email server. For an idiot (barely understood Linux back then), I don't remember it being that hard to set up. Then again, that was 20 years ago and things have probably changed.
Qmail is still the second most common daemon on the internet.

Yea things have changed. You've got no chance of running a mail server on dynamic dns. You'll be insta-blocked by every mail service as soon as they see no reverse dns, so spf record, a consumer allocated IP, listing on a DNSBL, or actually detect that the dns is provided dynamically.
