Clarification: the new UID must be greater than any value currently KNOWN LOCALLY in high_saved. Because of race conditions or network outages, the local high_saved table might be out-of-date with respect to other servers. That's OK, we'll compensate for it later. > (S7) When the user client connects and wants the last UID, first > perform step (S6). Correction: first perform step (S6) for the mailbox in question; don't need to waste time cleaning out the whole message table. - Morty
