Mail.Mod [also] uses UIDL in PROC Synchronize, and I also want to
know the detailed reasons, so I'm posting:
Subject: POP use of UIDL command ?
It's not clear to me from my RFCs: 1939, 1725, 2449 how the
[list unique IDs of mails still on the server] UIDL is used.
I'm speculating that when a list of mails is left on the server and the
client, then the ability to check/synchronize the 2 lists-of-mails is
needed. Provision must be made for the possibility of mail[s] being
deleted from either the server or client, without the corresponding
client or server deletion; which would cause a loss of synchronism.
Q - what would the alrogithm be for using such UIDL facility ?
ForEach ServerMail: Get the unique-ID;
Compare with the Client's listing & provide info. re. any miss-match.
Perhaps any mails which are on one only of the server and client,
would be marked as such ?
Forcing a synchronisation would need deleting the unmatched
Thanks for any info.
