VPOP3 Configuration

Occasionally, third-party security software will block VPOP3 from accessing our online licence activation servers using https. There is another knowledgebase article with some details about that here: https://helpdesk.pscs.co.uk/297320-Licence-activation-not-working Alternatively, you can enter the licence details into the database manually: At a command prompt in the VPOP3 directory run: For VPOP3 Basic vpop3settings set \licence\~key <licence key> vpop3settings set \licence...

There are instructions for this on our wiki (https://wiki.pscs.co.uk/how_to:encrypt_sessions). The one limitation currently in VPOP3 is that the IM...

If you want to be able to use your VPOP3 server on devices (e.g. phones & tablets) when they are connected to your office Wifi and also when they are outside the office, you need to be able to configure them so that they can access your VPOP3 server wherever they are. If your router supports NAT loopback (or NAT reflection), then you can simply use the external IP address, and you'll be able to access it from inside the office as well, however this can be slow with some routers so it is not alw...

Sometimes people want to be able to access their office VPOP3 mail server from a remote site or mobile phone etc. These instructions assume you have a permanent Internet connection (eg ADSL, Cable etc). If you don't have a permanent Internet connection, see here (https://wiki.pscs.co.uk/how_to:remoteaccessdialup) **Router/Firewall Configuration** First you need to set your router and/or firewall to allow incoming access to the VPOP3 computer on the relevant ports (eg 110 for POP3, 143 for ...
