failed to access user's Sieve script file

Hello!

I set sieve = file:~/sieve;active=~/Postfach/.dovecot.sieve because I got error Debug: sieve: user's script ~/.dovecot.sieve doesn't exist

But with sieve = file:~/sieve;active=~/Postfach/.dovecot.sieve I get

Jun 22 01:55:21 lda(a.meyer): Error: sieve: sieve file backend: invalid option `active=~/Postfach/.dovecot.sieve' Jun 22 01:55:21 lda(a.meyer): Error: sieve: failed to access user's Sieve script file:~/sieve;active=~/Postfach/.dovecot.sieve (temporary failure)

What can I do so that LDA finds the sievescript of the user?

Kind regards

Andreas
