configuring email?

savecancel

I configured my settings.py

ADMINS = (
  ('Matthew Harris', 'harris112@aims.info'),
)
... db stuff ...
outgoing mail server settings
SERVER_EMAIL = 'harris112@aims.info'
DEFAULT_FROM_EMAIL = 'harris112@aims.info'
EMAIL_HOST_USER = ''
EMAIL_HOST_PASSWORD = ''
EMAIL_SUBJECT_PREFIX = ''
EMAIL_HOST='nospam.aims.info'
EMAIL_PORT=''
EMAIL_USE_TLS=False
EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend'

and from that directory I can send an email to myself (admin email) with

from django.core.mail import mail_admins
mail_admins('subject line', 'message text')

but user are still not receiving emails (example creating an account verification email)

The server also sends mail find

mail -v 'harris112@aims.info'

Am I missing something? Any thoughts, ideas, comments, or concerns?
