How to stop sieve processing to skip sieve_after scripts ?

[Mr Nicolas Belan]

Hello the list,

I am trying to achieve filter processing using sieve, but i am not sure I can do what I want.
I want to let the user decide to use my filtering script (sieve_after) or not.According to the documentation, i am trying to stop processing in user sieve script, but processing continue.

I am using dovecot 2.2 (CentOS).
My sieve configuration is:plugin {
  sieve = /var/vmail/%d/%n/%n.sieve
  sieve_before = /etc/dovecot/sieve/global-before
  sieve_after = /etc/dovecot/sieve/global
[...]}
'sieve' is the filter script created by users. When trying to stop processing, it is generated by roundcube like:# rule:[deliver to mailbox]
if anyof (true)
{
    stop;
}

'sieve_after' is the filter which handles the spam processing (fileinto Junk).
But the processing continue until all sieve filters are processed:

I would like to stop processing afterMar 22 14:50:23 lda(user at example.com): Debug: sieve: using the following location for user's Sieve script: /var/vmail/example.com/user/user.sieve;name=main scriptAt the end, I do not want mail to be delivered into Junk, but into INBOX..
Is it possible ? Perhaps a sieve, sieve2 setting exists ? (like sieve_before, sieve_before2 ...) 
Thank you for your help, ideas :)
Best regards,
Nicolas
