Davmail headless doesn't work on Arch Linux?

Question

I'm using the AUR davmail package that comes with a systemctl script, similar to the one found here.

Unfortunately it doesn't work.

⚘ systemctl --user status davmail@wayne.service                                                                                                                                                                                                                                       9:44:58

When I try to run the same command that ExecStart uses:

⚘ /usr/bin/davmail /home/wayne/.config/davmail/wayne.properties                                                                                                                                                                                                                       9:54:11

I would really love to be able to actually run davmail without requiring a GUI (most notably because my Xorg ends out thrashing the CPU, but that's a different question). I've done some Googling around, to no avail (and davmail --help apparently isn't a command).

How can I get davmail working without an X display?

It sounds like you didn't set davmail.server=true in davmail.properties to tell it it's supposed to be headless.

See DavMail Setup as a standalone server.

Ugh. I actually found this today and added it... but it turns out I had a second occurence in my properties file. grep server ~/.davmail.properties showed me that I was setting it to true at the top and later it was being set to false. Doh! – Wayne Werner Apr 06 '16 at 18:43
