If the above suggestion was not clear enough, then the following
one may help:

Look for obvious signs of trouble
Postfix logs all failed and successful deliveries to a logfile.
The file is usually called /var/log/maillog or /var/log/mail; the
exact pathname is defined in the /etc/syslog.conf file.
When Postfix does not receive or deliver mail, the first order of
business is to look for errors that prevent Postfix from working
properly:
% egrep '(warning|error|fatal|panic):' /some/log/file | more
Note: the most important message is near the BEGINNING of the
output. Error messages that come later are less useful.
The nature of each problem is indicated as follows:
* "panic" indicates a problem in the software itself that only
a programmer can fix. Postfix cannot proceed until this is
fixed.
* "fatal" is the result of missing files, incorrect permissions,
incorrect configuration file settings that you can fix.
Postfix cannot proceed until this is fixed.
* "error" reports an error condition. For safety reasons, a
Postfix process will terminate when more than 13 of these
happen.
* "warning" indicates a non-fatal error. These are problems
that you may not be able to fix (such as a broken DNS server
elsewhere on the network) but may also indicate local
configuration errors that could become a problem later.
