hi,

@ imap login to 2.0/head,

Oct 12 21:06:53 master: Info: Dovecot v2.0.alpha1 starting up (core

Oct 12 21:07:16 IMAP(testuser at my.domain.com): Fatal: Couldn't load

also, after install, i note,

cd /usr/local/lib
ls dovecot/{imap,lda,pop3}
 dovecot/imap:
  lib15_notify_plugin.so

 dovecot/lda:
  lib15_notify_plugin.so  lib90_sieve_plugin.a  lib90_sieve_plugin.la
lib90_sieve_plugin.so

 dovecot/pop3:
  lib15_notify_plugin.so

shouldn't, e.g., dovecot/imap have auto-populated symlinks to
autocreate, fts, etc plugins? or for 2.0 do they need to be manually
created?

thx.
