Don't feed the animals. Generally, when one person is mail-bombing another, either there has been a fair amount of provocation by at least one of the parties, and escalation of childishness isn't as useful as trying to resolve some of your differences, though it can offer a certain amount of basic 4-year-old ego satisfaction. If somebody's mail-bombing you, and they're root, and they're not doing it anonymously, you don't need to either; the worst revealing your identity will do at that point is encourage them to mail-bomb you. And your system administrator probably already knows who you are by now, assuming the bombing has been at a high rate. If the bomber is root on his home machine, and the bombs include bad words that aren't mere reflections of your words to him, you could always complain to the phone company that you're receiving obscene phone calls. I doubt the policies or laws about that specify whether the calls have to be made in spoken English.... If the bomber is root on his business machine, you can complain to his management, assuming you can locate them. Some managers get very bent out of shape about this and do random clueless things, others conservatively protect their company images, others ask what state and federal laws have been broken and tell you to stifle yourself if the answer is "none". If the bomber is root on his home PC at a university, arbitrary randomness can occur. On the other hand, if you're really L- D-, and the person who is mailbombing you is Perry Metzger, expending large amounts of childishness in his direction will not accomplish anything positive for either of you, and if both of you start sending N copies of each others' mail to each other, exponential growth will not help either of your systems. If you're not really L- D-, but the person who is mailbombing you is still Perry, try talking rationally to him; he can do that just fine if he thinks it's worthwhile. If you're really L- D-, and the person is or is not Perry, we can help.
