User education is the best solution. You're not going to improve matters much by adding a POP3 proxy which refuses rapid connections compared with simply having them hit the normal POP3 daemon. On the other hand, you will see an improvement if you switch from using POP3 to using IMAP, as the latter protocol is more efficient about mailbox updates. (At least, if the client is sanely written.) -- -Chuck
