The .QDF files turn up in the SMTPMAIL directory on my Netware 4 server which has been there since 1996 when I first installed mercury.nlm .  I just continued to use it when I changed to Mercury32.  The files on my Netware server are not virus scanned.  I have scanners working on my Windows 2000 server and my workstations.  I guess the scanner on the Windows server could be operating when Mercury32 accesses the Netware directory.  I think I have just reconfigured the scanner to skip the queue directory.  We shall see.

 Thanks

My installation of Mercury32 v4.52 performs faultlessly most of the time and then occasionally, and intermittently, gets confused.  Symptoms are:  1 the SMTPMAIL outgoing queue directory gets overrun with orphan .QDF files; 2 Mercury32 queue directory can get overloaded with stray files; 3 Mail gets apparently sent but recipients report headers received with no message content.

 I can always cure it by stopping Mercury - deleting unwanted files in the queue directories and re-starting Mercury.  However, sod's low decrees that it i s always when there is a critical email to send that looks as though it has been sent properly and in fact has not been sent and this isn;t discoverd for a day or two and serious consequences ensue.

For years I used the Netware NLM version of Mercury which never gave a problem.  I only ditched it because not having a resolver it got in a mess every time my ISP re-built their mail server and changed its IP address.  In contrast Mercury32 seems a fragile piece of programming, easil upset and confused.  I am disappointed with it.

This is not a normal behavior for Mercury/32. It sounds like some other process on the server is interfering with Mercury's access to mail files. This can happen with for instance anti-virus programs and software that adds some kind of restore function for deleted files. At least Mercury's queue and scratch directories should be excluded from any real time virus protection, and it may sometimes be necessary to exclude all Mercury directories including mailbox directories. Instead scan incoming messages with Clamwall or some other anti-virus program that can be integrated with Mercury.
