Ask HN: How do you forward your email addresses?

I have many domains that I have purchased over the years and I use Hover.com to maintain them. Their email forwarding services seem very limited. I run mu own postfix server but I usually end up forgetting to run postmap service restart when, approximately once a quarter, I'm adding a new domain for a new landing page.

I also tried to give every company I interact with a "burnable" email address so I can just switch off their spam easily (and use + syntax to file them too), but its always ended up being a hassle to set up easily.

Am I the only person with this problem? Am I missing an obvious solution?
