[Dovecot] dovecot crashes after reloading service

[Alan Morais]

Hello,

I just made a fresh install of dovecot using Iredmail, and works just 
fine,
but, after changing a parameter on /etc/dovecot.conf, and reloading
service, the daemon crashes, with the message as follows:

* restarting the service instead of reload works fine.

############# Error message
