causes problems under Windows if the certificate changes

[ClusterWood]

... causes problems under Windows if the certificate changes. Solution:

Delete '...\AppData\Roaming\sieve'

Install sieve-0.5.2. Add server again, certificate warnings can be skipped here. Login: “Force PLAIN”; when everything is running again, install version sieve 0.6.1. Runs somewhat more stable than 0.5.2, but cannot handle certificate changes.

Good luck
