sievescript is not working

[ratatouille]

Hello!

I have a problem with a sieve-script which works for one domain but not for another one.
Both domains are hostet on the same server running dovecot and postfix.

This is the script that works:

require ["vacation"];
# rule:[Out of office]
if true
{
        vacation :days 1 :addresses "a.meyer at nimmini.de" :subject "absent" "Ich bin nicht da.";
}

This one does not, a vacation message is not sent:

require ["vacation"];
# rule:[Out of office]
if true
{
        vacation :days 1 :addresses "a.meyer at bitcorner.de" :subject "absent" "Ich bin nicht da.";
}

I don't know why. A sieve-test shows

# sieve-test ./managesieve.sieve ./testfile -D
sieve-test(andreas): Debug: sieve: Pigeonhole version 0.4.2 initializing
sieve-test(andreas): Debug: sieve: include: sieve_global_dir is not set; it is currently not possible to include `:global' scripts.
debug: script binary ./managesieve.svbin is not up-to-date.
debug: script `managesieve' from ./managesieve.sieve successfully compiled.

Performed actions:

 * send vacation message:
    => seconds : 86400
    => subject : Nicht im Büro
    => handle  : Bin bis zum 25.06.2018 nicht im Büro. Email wird beantwortet, sobald ich wieder zurück bin.Nicht im Büro<default-from><NO-MIME>

START MESSAGE
Bin bis zum 25.06.2018 nicht im Büro. Email wird beantwortet, sobald ich wieder zurück bin.
END MESSAGE

Implicit keep:

 * store message in folder: INBOX

sieve-test(andreas): Info: final result: success

Any help appreciated!

Kind regards
