Well I gave it a good go, I tried to get support here, nobody seems bothered about anything that doesn't work or things that work and get truncated. Nobody seems phased that Google's pop3 client can't connect to Mercurys pop3 server, nor worried about the error logs that are truncated half way through an error message leaving nothing to work with.. So I've dumped Mercury (and deleted it) and made the switch to hmailserver. Works flawlessly and even redirects mail to another server on another port - I can use that to the fullest. If anyone else reads this and wants to do the same, your windows server will need dotNET 2 and 3 installed. If you can't install it then you need to allow the windows update service to run (plenty of help on this via google). Once that's done, it's a great bit of kit to use and runs as a service with its own remote control GUI program. No restarts needed. It's also open source and has a webmail! Best wishes, Dinky
