No. It must be greater than any value known to any client. If a client connects to host A then host B that both have the same UIDVALIDITY but host A has a gap where host B has a message, that client will NEVER download that message from host B. > > (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. Clients don't want UIDs, they don't ever get allocated UIDs, I don't understand this. -- Internet Connection High Quality Web Hosting http://www.internetconnection.net/
