If the POP daemon only deletes mail, and don't write any new information
to the mbox, it doesn't need to keep a copy of every mail in memory.
However, in case of an abnormal exit, due to a crash or whatever, the
user may lose up to one mail and have an corrupted mailbox. This risk
may or may not be acceptable. I believe cucipop was, at least one of,
the first POP daemon to embrace this.
