It is just a sieve rule.

On disk default file .dovecot.sieve

2. I am using roundcube webmail for that.

3. with if false # true
# rule:[Out of Office]
if true

     vacation :days 1 :subject "Test" "test test";
}

Hi all,

I have a legacy system that uses gnarwl to handle vacation messages, 
most specifically the vacation messages are stored in LDAP. We have a 
web based tool that allows people to update their vacation message, all 
they’re doing is modifying LDAP.

I am trying to find out if dovecot’s vacation sieve can do the same 
thing. I am struggling however to find something that describes to me 
how dovecot vacation sieve is configured. Is there a howto or 
walkthrough anywhere?

Specific burning questions:

- If I was to configure the dovecot vacation sieve, where is the body of 
each vacation message stored? File on disk? In a store like an LDAP 
store? Somewhere else?

- How is the body of vacation message modified? Does this  happen 
through the IMAP protocol, a command line tool, something else?

- How is the vacation message switched on and off? Does this happen 
through the IMAP protocol, a command line tool, or something else?

The docs at 
https://wiki2.dovecot.org/Pigeonhole/Sieve/Extensions/Vacation describe 
how to control how often the vacation messages are sent, but very little 
else. I am very confused :(

Regards,
Graham
