[Dovecot] Better flagging of errors on logs?

[Francisco Reyes]

Last night dovecot died because of time changed backward.
I noticed that the line from dovecot read

Oct  9 01:00:44 mailstore16 dovecot: Time just moved backwards by 132 
seconds. This might cause a lot of problems, so I'll just kill myself now.

Shouldn't such lines have the word "Error" or "Fatal"?

If I set the log_path = to a file, will syslog messages still be generated?
