Actually, you most definitely want to quote that glob, using "*.log" or '*.log' or \*.log. If unescaped, the shell expands that glob before the find command ever sees it. That command worked because there were no matches to *.log in the current directory, which from the looks of it is the top level /. When there are no matches, the shell leaves the pattern as is. Had there been one match, find would have been looking for a file with that specific name throughout the entire file hierarchy. Had there been multiple matches, the glob would've been expanded by the shell into a list and most likely would've lead to a find syntax error.

An illustrative example with sh tracing enabled (after `set -x`, each line beginning with a "+" is the command that the shell is actually executing):
Code:
$ mkdir tmp
$ cd tmp
$ ls -a
.       ..
$ set -x
$ find . -name *.log
+ find . -name '*.log'
$ touch 1.log
+ touch 1.log
$ find . -name *.log
+ find . -name 1.log
./1.log
$ touch 2.log
+ touch 2.log
$ find . -name *.log
+ find . -name 1.log 2.log
find: 2.log: unknown expression primary
$ find . -name \*.log
+ find . -name '*.log'
./1.log
./2.log

doveadm-log

DOVEADM-LOG(1)							      Dovecot							    DOVEADM-LOG(1)

NAME

       doveadm-log - Locate, test or reopen Dovecot's log files

SYNOPSIS

       doveadm [-Dv] log errors
       doveadm [-Dv] log find [directory]
       doveadm [-Dv] log reopen
       doveadm [-Dv] log test

DESCRIPTION

       The  doveadm  log commands are used to locate and reopen the log files of dovecot(1).  It's also possible to test the configured targets of
       the *log_path settings.

OPTIONS

       Global doveadm(1) options:

       -D     Enables verbosity and debug messages.

       -v     Enables verbosity, including progress counter.

COMMANDS

   log errors
       doveadm log errors

       The log errors command is used to show the last	- up to 1,000 - errors and warnings.  If no output is generated, no errors  have  occurred
       since the last start.

   log find
       doveadm log find [directory]

       The  log  find  command	is used to show the location of the log files, to which dovecot(1) sends its log messages.  If dovecot(1) logs its
       messages through syslogd(8) and doveadm(1) could not find any log files, you can specify the directory where your syslogd  writes  its  log
       files.

   log reopen
       doveadm log reopen

       This command causes doveadm to reopen all log files, configured in the log_path, info_log_path and debug_log_path settings.  These settings
       are configured in /etc/dovecot/conf.d/10-logging.conf.
       This is for example useful after manually rotating the log files.

   log test
       doveadm log test

       This command causes doveadm to write the message "This is Dovecot's priority log (timestamp)" to the configured log files.  The used prior-
       ities are: debug, info, warning, error and fatal.

EXAMPLE

       This example shows how to locate the log files used by dovecot(1).

       doveadm log find
       Looking for log files from /var/log
       Debug: /var/log/dovecot.debug
       Info: /var/log/mail.log
       Warning: /var/log/mail.log
       Error: /var/log/mail.log
       Fatal: /var/log/mail.log

REPORTING BUGS

       Report  bugs,  including doveconf -n output, to the Dovecot Mailing List <dovecot@dovecot.org>.	Information about reporting bugs is avail-
       able at: http://dovecot.org/bugreport.html
