Reposted from another post of mine:
Essentially, it's not legal, but it boils down to which agency of the government you want to run afoul of and what is the liklihood of enforcement, siezure, or civil or criminal fines.
1) It is against Federal law to ship alcohol via the USPS.
2) It's against policy to ship alcohol via Fed Ex, DHL, UPS unless you are a valid shipper of alcohol. If your package breaks, they may turn your package to your state's alcohol control board or they may return it to you, or they may dispose of it, or they may re-pack it and ship it. You are at the mercy of that employee.
3) It's undoubtedly against state law (UT inparticular) to ship beer. I read on realbeer that UT's ACB has siezed likely alcohol shipments. Google it.
4) It's against the law to ship alcohol to minors.
5) It's against the law to ship alcohol to another country without using a customs approved shipper. See beertown.org for information about their world beer contest.
So don't do #1 or #4 or #5. If you do #2, make sure your package is bulletproof. Don't identify the contents as alcohol. Dont' get insurance, etc.
#3.... just move.
Deny everything.
