Hi everyone,

In the following configuration my IMAPSieve script doesn't run on the configured "copy" action when I assign it to a virtual mailbox.

However, using the very same config snippet on a regular mailbox, the script suddenly starts to work. Move direction: from virtual to virtual (INBOX/Primary to INBOX/Notification).

Do you know how to assign IMAPSieve to virtual mailboxes?

Virtual config:

namespace virtual-classification { prefix = "INBOX/" separator = / mail_driver = virtual mail_path = /var/lib/dovecot/virtual/classification/en mail_index_path = %{home}/index/virtual/classification/en namespace_subscriptions = no

  mailbox Notification { auto = subscribe

    sieve_script classification-move1 { type = before cause = copy append path = /var/lib/dovecot/sieve/imapsieve.d/classification-move.sieve } } mailbox Primary { [...] } }

Sieve script:

require ["vnd.dovecot.debug"]; debug_log "IMAPSIEVE SCRIPT WAS CALLED!";

Virtual file:

virtual/classification/en/Notification/dovecot-virtual: !INBOX KEYWORD classification-notification

The same result with "!INBOX" and "INBOX".

Inbox namespace (working example):

namespace inbox { separator = / inbox = yes mail_path = %{home}/mail mail_index_path = %{home}/index/inbox

  mailbox "Archive" { special_use = \Archive auto = subscribe

    sieve_script classification-move1 { type = before cause = copy append path = /var/lib/dovecot/sieve/imapsieve.d/classification-move.sieve } } }

In the latter case the script is called properly and I see the debug message in info.log.

But in the virtual case, the script doesn't run. Debug logs of failing case:

IMAPSieve config seems to work (based on the successful regular mailbox example), so I don't paste the whole sieve config (but in case it's necessary, I'll do it).
