At least I read it like that.This is drifting pretty far away from mutt, and I doubt any of us are writing new POP client code, so I'll keep this shortish. :) I imagine that I understand why the draft suggests a mailbox lock, but I think it's wrong to interpret that as a real requirement of POP. RFC 1939 predates BCP-14 (RFC 2119) and no MUST/SHOULD is present. Absent such terminology (and reasons for using it) I think that a protocol RFC doesn't get to prescribe the exact behavior of the server as long as the interface goals are met, and this can be done without an exclusive lock on the whole mailbox. What 1939 describes may be necessary for some server implementations, but not for all. -- -D. d...@uchicago.edu NSIT University of Chicago Just to clear the deck, I own no monkeys.
