Sending email connection error

[dbv]

Running the simple_webapp.py example starting with the signup (register) process using my email providers smtp url.  Getting a connection failed error and not sure where the problem is.  Here is the error message:

Hi. This is an error from the socket module.
If the problem is not persistent, looks like your mailserver was not
responsive at the time.
Otherwise, make sure that the configuration string (protocol, server
name, port number) is correct.

It is persistent.

Should the argument list for Cork() __init()__ include: proto=None and port=None ?

Still doesn't send registration email ... uhmm!

You can use smtp_url as:
<protocol>://[<username>[:<password>]@]<fqdn>[:<port_number>]/
where protocol can be: smtp, starttls, ssl
Username, password, port_number are optional.

Here is an example:
https://github.com/FedericoCeratto/bottle-cork/blob/master/examples/simple_webapp.py#L19

I'll update the documentation accordingly.

Still not working but here are some clues:

a) The email account I'm using requires username/password authentication.  But, the username is an email address which the Mailer regex doesn't parse correctly.

b) SMTP_SSL from smtplib might be better but won't know for sure until a) is fixed.

Thanks for the bugreport. SMTP usernames may contain "@" and the
Mailer regexp should be able to handle that.
The "url" syntax is used similarly by other applications, e.g. mutt:
http://durak.org/sean/pubs/software/mutt/optionalfeatures.html

SSL mode is not supported at the moment (but implementing would
probably require a short time):

a) If the username contains "@" then it does break the Mailer regex.  Debugged by printing-out d = match.groupdict() which shows that it breaks.

b) I tried with SMTP_SSL and the program moved further then with SMTP but failed at a).  If a) is fixed then maybe using SMPT_SSL will work and solve the original problem.

Ok, the regex (in the development branch on Github) is now able to
handle the at sign in the username.

Also, SSL is implemented.

Testing and feedback is welcome!

a. Mailer regex

Works perfectly.

b. Email sent?

No.  

In cork.py, because the username:password are sent in the smtp string, I added:

 

user = self._conf['user']

and the check:

if user != "": instead of if proto == 'ssl':

And, this sent the email.

Testing simple_webapp.py on EC2 instance with:

bottle.run(app=app, host="myec2site", port=80, quiet=False, reloader=True)

where myec2site points to the IP address in the hosts file, and got the error:

error: [Errno 99] Cannot assign requested address

Posted on Bottle group too.  Any ideas?

[dbv]

I guess Bottle does not support alphanumeric host names in hosts files?

Also tried:

1. bottle.run (host = 'xxx.xxx.xxx. xxx ', port = 80) where xxx.xxx.xxx.xxx = EC2 public IP address.

The error is: socket.error: address [Errno 99] Can not assign requested address

2. bottle.run (host = '0 .0.0.0 ', port = 8080)

Says, listening on http://0.0.0.0:8080/ but entering EC2 public IP address xxx.xxx.xxx.xxx browser does not find page.

Any ideas what the problem could be?

[dbv]

My bad: port 0.0.0.0:8080 wasn't opened at the EC2 and so it now works.  However, we want to use the EC2 public IP address in a IP:PORT combination and I guess that is supported when we replace the bottle standard server with Nginx, for example?
