[Dovecot] How to check for keywords in IMAP store?

[Steffen Kaiser]

Hello,

I'm checking my way to migrate from Courier to Dovecot. Wiki says that 
"there's currently no easy way to migrate them [the keywords]".

Frankly, I lack the information to check if some client is using keywords 
at all. More importantly, is it OK to assume that when

SELECT INBOX

returns no \* in  OK [PERMANENTFLAGS ...]
that the IMAP server does not allow keywords at all?

[BTW: Is there a searchable mail archive of the Dovecot list?]

Bye,
