[Dovecot] Sieve problems (not matching emails expected to match)

[Michael Welsh Duggan]

Problem solved.  Apparently this comment in my lda configuration lied.

protocol lda {
  # Space separated list of plugins to load (default is global mail_plugins).
  # mail_plugins = $mail_plugins
}

I had to set this to

protocol lda {
  # Space separated list of plugins to load (default is global mail_plugins).
  mail_plugins = $mail_plugins sieve
}

despite the fact that mail_plugins includes sieve.
