i right click the account in the sources window, otherwise the same.

but following your recipe exactly
  - does not jump into alpha sort
  - and if i quit mailmate and restart, it is not visible.  i have
    to Edit Subscriptions and check it and commit
  - it has always been this way for me

14.2.1 and MM Version 1.14 (6010)
