This reduces the complexity for handling + a large UIDL from O(n^2) to O(n log n) and becomes noticably faster with + thousands of kept messages. (IMAP does not track UIDs and is unaffected.) + At the same time, the UIDL emulation code for deficient servers has been + removed. It never worked really well. Servers that do not implement the + optional UIDL command only work with --fetchall option set, which in itself is + incompatible with the --keep option (it would cause message duplication). ## FIXES * Fix a typo in the FAQ.
