I'm finding the 30 alias limit to be constraining. I currently create an alias for every bank, online service, email list, etc. That way, when I quit that service but they continue to contact me I can just delete the alias. This is especially useful when doing something like buying a car--I can get quotes, make the deal, and then delete the alias stopping all the follow-up sales emails.
I would like to request the alias limit be raised to something more flexible, like 100.
Thanks!
