[Dovecot] startup script under FreeBSD 6.2 / dovecot-1.0rc22

Hi all,

I recently installed Dovecot rc22 from the FreeBSD ports and I have
some problem with the dovecot startup:

• If I start dovecot manually, it works fine, it starts and I get
  messages in /var/log/maillog
• If I reboot the machine, that's where the problem appears, dovecot
  doesn't seem to start and I get nothing, no errors in /var/log/maillog

Any idea if this is a known problem and how to fix it ?

Thanks in advance, Regards,

Alexis
