I'm surprised this is still biting people. I setup internet connectivity for a local CC about 1994. At that time the docs I read said that _ was going away and was not going to work in future systems. I told the peole cat the college that they had several machines with an undercore in them, and they should make plans to change them, so you can't say this was an entirely unexpected thing - except for those who don't read the information. Of course at that time there were problems with domains with a numeric as their first character - eg 3com for example Bill -- Bill Vermillion - bv@wjv.com.
