Bug 407465

SUMMARY

KMail's sieve script editor seems fine, but it doesn't ever seem to activate the sieve scripts at all. It does put the active scripts in the USER script, which is great, but it never sends the managesieve SETACTIVE command.

I am using Dovecot 2.3.4.1. In the default dovecot configuration the active sieve script is stored as a symlink .dovecot.sieve -> sieve/USER.sieve, 
otherwise NO sieve scripts are active.

It is possible to work around this by connecting to the managesieve port, logging in, and doing SETACTIVE "USER" yourself, so it is not a problem with Dovecot.

STEPS TO REPRODUCE
1. Add an imap account in KMail with sieve enabled
2. Add a sieve script
3. Try to enable script

OBSERVED RESULT
No active sieve script: KMail lists all scripts as disabled and the symlink that
dovecot creates to indicate the active sieve script is missing.

EXPECTED RESULT
Kmail should list scripts as enabled and the symlink that dovecot creates
to indicate the active sieve script should be present.
