I used to have a (Rust!) program running on my e-mail server that 
allowed me to send a special e-mail to a special address and it would 
create a new alias for me, and send a confirming e-mail back to me. Easy 
enough to do while waiting in line for a rental car, or the like.

Alas, I don't have it running at the moment because I have a hacky dual 
server system running (did I say my DSL has gotten unreliable?) and I 
need to update it to work across two servers, keeping the alias files in 
sync. I have it mostly figured out (crafting for idempotence makes such 
things easier), but I haven't programmed it yet.

All possible because I run my own e-mail server.

P.S. I have an alias I used to order some spare parts from Sony...and 
then they leaked it and now it is all spam.
