True you may not be able to guess the actual location, but you can make an attempt at a guess. Besides multiple optimals, various reasons may make itnot at that location. For example, UORVM does not seem to have accurate mailer tables, so I keep getting rejections from lists at UTORONTO or CANADA01. Rather than getting that rejection mail, I moved the people back to MARIST. (And complained to the postmaster at UORVM). If I add a new peer to a list, I may forget to explode a given list, etc. There can be a hundred reasons you won't guess the correct server, but I think a fair attempt should be made. As Ross said, you always have IGOR (GLOBAL) to go out and get the person it needed. For the case of more than 1 optimal server, I don't care. Either pick one of the possible choices, or send to all of them. I don't care which. I think advantages in the majority of the cases will be 1 peer, and that will be a significant number of the deletes. Harry
