-/// An internal Mail Identifier is composed of two components:
-/// - a process identifier, 128 bits, itself composed of:
-///   - the timestamp of when the process started, 64 bits
-///   - a 64-bit random number
-/// - a sequence number, 64 bits
-/// They are not part of the protocol but an internal representation
-/// required by Mailrage/Aerogramme.
-/// Their main property is to be unique without having to rely
-/// on synchronization between IMAP processes.
