Quitting mailspring doesn't end all processes


On Linux, when quitting mailspring, then checking in the process manager, processes called main are not closed, the ones started with the following command line /usr/share/mailspring/resources/app.asar.unpacked/mailsync.bin--modesync--info mail@provider.xyz

Restarting Mailspring creates new such processes and the old ones stay there, apparently indefinitely.

To Reproduce…

Steps to reproduce the behavior:

  1. Open Mailspring
  2. Quit Mailspring.
  3. Check for alive processes ones still associated with mailspring

Expected Behavior

After quitting mailspring, no process should be left open.


  • OS and Version: Archlinux and Ubuntu 20.10
