Location of dovecot.sieve

Hello!

If I set sieve = file:~/sieve;active=~/.dovecot.sieve

in dovecot.conf like I read in the documentation I get

Jun 22 16:36:01 lda(a.meyer): Error: sieve: sieve file backend: invalid option `active=~/.dovecot.sieve' Jun 22 16:36:01 lda(a.meyer): Error: sieve: failed to access user's Sieve script file:~/sieve;active=~/.dovecot.sieve (temporary failure)

What is wrong with this one?

Kind regards

Andreas
