[Dovecot] Problem with SSL

[Артемьев Артем]

Freebsd 
dovecot --version
1.0.beta9

 In /usr/local/etc/dovecot.conf

#grep -i ssl /usr/local/etc/dovecot.conf |egrep -v '^#'
ssl_disable = no
ssl_cert_file = /etc/mail/certs/server.crt
ssl_key_file = /etc/mail/certs/server.key
ssl_parameters_regenerate = 24

 When I try to be connected to imaps I get message in maillog:

Jun 24 04:00:18 alife dovecot: imap-login: Waiting for SSL parameter
file /usr/local/etc/dovecot-ssl-parameters.dat

 Also I deleted a file /usr/local/etc/dovecot-ssl-parameters.dat and
reboot system. And file rebuild but still ssl doesn't work.

 I try 
# /usr/local/libexec/dovecot/ssl-build-param /usr/local/etc/dovecot-ssl-parameters.dat
SSL parameters regeneration completed

 And ssl doesn't work and I still get message 
Waiting for SSL parameter file /usr/local/etc/dovecot-ssl-parameters.dat

 I do not know what to do. 

 I have another server with 1.0.beta8 and ssl work fine.
