How do I make "vnd.dovecot.environment" available?

[Graham Leggett]

Hi all,

According to the docs at https://wiki.dovecot.org/Pigeonhole/Sieve, some extensions are not available by default.

The docs tell me the sieve_plugins, sieve_extensions and/or sieve_global_extensions configs are involved, but I can find no authoritative documentation as to what the values should be.

What values must I use to make “vnd.dovecot.environment” available?

Adding "sieve_global_extensions = +vnd.dovecot.environment” to 90-sieve.conf seems to not be enough.

[root at gatekeeper ~]# sievec -D /var/lib/dovecot-sieve/default.sieve 
sievec(root): Debug: sieve: Pigeonhole version 0.5.8 (b7b03ba2) initializing
sievec(root): Debug: sieve: include: sieve_global is not set; it is currently not possible to include `:global' scripts.
