Bluemail and Thunderbird both work fine.

It turns out it wasn't quite the VPN. It was the country I had the VPN set to, the Netherlands. When I changed to Germany the problem went away. Now everything works fine.

It seems odd that they're blocking access to my SMTP but not IMAP, but whatever. Problem solved.

This is a common problem with VPNs, as they interrupt the process of sending mail. Look into the settings for the VPN to find how to bypass checking mail.
