Since LISTSERV doesn't recognize the two addresses as being identical it can't issue that warning. As far as it is concerned, there is no pending request from the user who sent the OK command. Again, mail systems that use a different address depending on day of week are going to cause problems anyway. If you bought a Cray to run an AI system that would identify the OK confirmation 99.99% of the time, you wouldn't have solved the problem or got rid of the user because he'd come back just 2 days later and say "I tried to switch to digest and LISTSERV says I'm not on the list!!!!".
