I still have to disagree with you on this. My qpopper daemon, doesn't allow the use of retrying (as used with the previous example).

# first try, without calling quits
$ telnet *host* 110
Trying *host*...
Connected to *host*.
Escape character is '^]'.
+OK Qpopper (version 4.0.5) at *host* starting.  <76162.1072222944@*ho
+st*>
user *user*
+OK Password required for *user*.
pass invalidpass
-ERR [AUTH] Password supplied for "*user*" is incorrect.
+OK Pop server at *host* signing off.
Connection closed by foreign host.

# second try, now calling quit
$ telnet *host* 110
Trying *host*...
Connected to *host*.
Escape character is '^]'.
+OK Qpopper (version 4.0.5) at *host* starting.  <76181.1072223079@*ho

+OK Password required for *user*.
pass invalidpass
-ERR [AUTH] Password supplied for "*user*" is incorrect.
quit

The daemon allows some time for a quit command, before dropping the connection. So far I have tested 4 POP3 daemons:

All of the above allow some time before they disconnect (if they do it at all). Unfortunally, POP3 daemons are allowed to drop the connection straight after an invalid password, according to RFC1939:

"After returning a negative status indicator, the server may close the connection."

So, I'm affraid the OP is dealt some wrong cards. In general, would it be bad to "quit" a connection, even if there's a bad login? Based on my testing experiences, I tend not to believe that.
