Email subsystem gets NPE at start

[arnieaustin2]

My SMTP server is MS Exchange. I can log into the Outlook Web App using the credentials as below:

mail.host=smtp.x.y
mail.port=25
mail.username=alfrescosystem@x.y
mail.password=secret
mail.encoding=UTF-8
mail.from.default=alfrescosystem@x.y
mail.protocol=smtp
# mail.smtp.auth=true
mail.smtp.timeout=30000
mail.smtps.auth=true
mail.smtps.starttls.enable=true

with or without smtps I get the same error and the information in the log isn't every helpful. How can I get more information as to what is going wrong?
