Hello, I just wanted to thank people who answered to my question of some days ago, reported in the subject of this email. I must say that the problem I reported never happened again, which means that maybe I was just a bit too sleepy :-() There is one thing I would like to point out however. The reason why I (or anybody else) would define mailboxes in this primitive way: > mailboxes ! =IN.list1 =IN.list2 =IN.list3 =IN.list4 =IN.list5 rather than with any of the versions kindly posted using ls, like: > mailboxes ! `/bin/ls ~/Mail` is that ls returns the mailboxes in ~/Mail, in alphabetical order, while the first version allows you to define the order in which you want to visit them, whichever that is. Ciao, Marco Fioretti
