Re: Missing IMAP METADATA Plugin

The configuration that I saw at the link you posted is the following, i.e.
not the one that you posted:

protocol imap {
  imap_metadata = yes
}

You're right, there's an extra "mail_plugins {}" section in my snippet. I must have copied it from somewhere else and didn't notice this extra section when compared with the doc.

When I removed it and configured the rest, it works nicely.

Thank you for the hint,
