[Dovecot] Problem after upgrade dovecot v2.0.8

[Wilberth Perez]

Hello,

upgrade Dovecot from v1.2.10 to v2.0.8, after build a new configuration
file following instructions of http://wiki2.dovecot.org/Upgrading/2.0

run dovecot I get this:

auth: Error: Fatal: Dovecot version mismatch: Master is v2.0.8,
dovecot-auth is v1.2.10 (if you don't care, set version_ignore=yes)
log: Error: service(auth): child 3389 returned error 89 (Fatal failure)
master: Error: service(auth): command startup failed, throttling

Did any SSL configuration is missing?

I am currently authenticating with dovecot and postfix.

Any knows , how could i solved this problem?

Thanks.
