Under 'Configuring Sender-Dependent SASL authentication', it says:

http://www.postfix.org/postconf.5.html#enable_long_queue_ids says:
"For safety reasons the vowels (AEIOUaeiou) are excluded from the
alphabet." In what way are vowels unsafe?
I can see why certain letters might be avoided in order to avoid typos

http://www.postfix.org/postconf.5.html#mydestination
--- a/conf/main.cf
Not too sure what the problem is, but I had to use '127.0.0.1' in place of

/etc/hosts ('127.0.0.1 localhost.localdomain localhost'), and
a 'ping localhost' at the command line works.
This is the line in the log t
