This is a standard POP3 option.

Normally an email client will get the list of messages with something like 
LIST, retrieve each message RETR, and finally delete the message with DELE.

If your email client and server support it, it can change the exchange to 
use UIDL instead of LIST to get a unique identifier for each message so the 
client can track which messages it has already received and skip the DELE 
for each message. The client may also be configured to delete messages from 
the server after a certain time (say 30 days).
