First of all: I appreciate your honest and competent answers very much - that's one of the reasons we decided to productively deploy Mercury in our company (Healthcare - and Yes, we purchased an unlimited license;).
I could reproduce the behaviour in our testenvironment: Win2003 Server, XP SP2 Clients - Mercury 4.52 upgraded to 4.61 - User-Mail-Directories and Mailqueue residing on separate partition (RAID-Mirror) - Clients configured to leave mails on the server until deletion. MercuryP default config (General: Port 110, Timeout 60, Refuse access without PWD - Global: First and last option checked).
