failed to access user's Sieve script file

[ratatouille]

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
