dovecot - Aug 2012 - bcrypt again

Hi

I'd like Dovecot to consume a list of users exported from an external
application which stores bcrypted passwords.

This has been asked in the past, however, I'm not sure how to read the
following reply:

I'm on Dovecot 2.0.19. Does this mean that only the hashes listed with
"doveadm pw -l" are supported and even if glibc can do bcrypt, the
CRYPT scheme won't do the trick anymore?

Thanks for your help!

{CRYPT} means that the password is put through libc's crypt() function. If
your libc's crypt() supports bcrypt, then Dovecot supports bcrypt.

I don't know why (whoever) said "<2.0".
