[Stephan Bosch (stephan-rename-it)]

Dovecot 1.2.9 is pretty old already. This bug is fixed in upstream ManageSieve:

http://hg.rename-it.nl/dovecot-1.2-managesieve/rev/96caf5265f07

[Christoph Fink (christoph-fink)]

Klaus:

I don’t know whether that helps you, but it helped for me to restrict the AUTH-methods to just 'PLAIN' in the client (in my case the roundcube webmail plugin, also I restricted access to localhost anyway)

[Chuck Short (zulcss)]

This is fixed in natty.
