[Dovecot] blf-crypt

[Patrick Domack]

BLF-CRYPT has been part of glibc for a very very long time. it uses  
the blowfish crypt version, that have been changed like 4 times now,  
do to issues with it.

I'm not sure why CRYPT wouldn't work for you, seems to work fine in my  
dovecot installs.

I'm not sure where the dovecot < 2.0 can use {CRYPT} came from. I'm  
using that, since 0.7x? or somewhere around there, all the way up  
through, and currently 2.1.7 without issue.
