On further evaluating eMClient, it appears this does not work with NordVPN. This is a real pity - so you’d need to make a conscious decision to sacrifice security in the name of getting access to the mail client. Not something I’m willing to do sadly.
What makes this much worse is that the eMClient devs just tell you to turn off the VPN if you want to use their product! Yet, Outlook, Betterbird/Thunderbird, Mailbird etc all work fine with NordVPN.
This lacklustre approach to security means I can’t use eMClient. A potential “solution” to this is to use the NordVPN browser extension rather than the Windows client, but that just means you’re only protecting the browser traffic and nothing else.
How is this an acceptable response from a software vendor who charges to use their app?
