Flask Mail Woes

Hi!
I posted a while back with help on my configs, I beleive they are sorted 
but im having a hard time moving forward. I was wondering if I could bug 
you for more help. 
This is my config:# MAIL SETTINGSMAIL_SERVER = 
'email-smtp.us-east-1.amazonaws.com'MAIL_PORT = 25MAIL_USE_TLS = 
TrueMAIL_USE_SSL = FalseMAIL_USERNAME = 'USER'MAIL_PASSWORD = 
'PASS'#MAIL_DEBUG = app.debugDEFAULT_MAIL_SENDER = NoneMAIL_DEBUG = 
FalseDEFAULT_MAIL_SENDER = NoneMAIL_FAIL_SILENTLY = False
This is the code that fires it:def send_confirmation_email(post):    if 
not post.email_invoice_address:        return False
    recipients = [post.email_invoice_address]    msg = Message('Posted 
juccessfully',                  body='Posted: %r' % post,
recipients=recipients)    try:        mail.send(msg)    except:  # Dont 
let SMTP errors take down the application. Should log error here        
return False    return True
Now, for the life of me I dont even know where to start debugging it, all 
I know is it doesnt work. The details in the config are correct, I know 
that much. Is there anything glaringly obvious wrong with this and how can
I move forward trying to debug this?
Thank you!

Hi James,

The only glaringly obvious error I can spot is post.
email_invoice_address (you shouldn't have a space between the . and
e).  Not sure if that's a typo from your code or a typo from typing it
into email.  Anyway, can you remove the try and except blocks and see
if there are tracebacks when attempting to send email?

Regards
Nigel

Actually, white space before or after the dot for attribute access is 
valid Python syntax. (Although it can be bad style.)

This is more probably what is swallowing the error.

You have fail silently turned off, which is good, but this except: is 
swallowing any errors. Without seeing your logging code I can't tell if 
it's properly recording the exception, but the first thing I'd do to 
debug is remove the try/except completely and see what flask-mail 
throws for exceptions.
