Re: Verify Emails

If you do your own email-sending code you can break off the sending after
the server sends "RCPT', that'll work regardless.

Re: Verify Emails

2018-04-07 Thread 'Anthony Flury' via Django users 

why not use an email validator provided by Django ?

https://docs.djangoproject.com/en/2.0/ref/validators/#emailvalidator

The problem with the pypi module is that to validate that an email 
exists it simply looks for server in DNS (which is slightly better than 
the Django validator), but that doesn't mean that the :


 * Email server will accept emails from you - or your service
 * or that the user exists on that server ( even if the server exists).

The only real way to validate that an email server is entirely valid is 
to send an email to it, asking for a reply. Email parsing will only go 
so far.


In theory there is a defined protocol to allow clients to  query email 
servers for is valid email addresses - but most servers are set to 
ignore those requests - for obvious reasons.

Re: Verify Emails

2018-04-07 Thread Jani Tiainen 
Hi,

Nothing prevents you to create django validator that does use that package.

Including functionality that package provides would add more dependencies
to Django (pyDNS) which greatly reduces chances to get existence
verification into Django itself.

And Django already has email validator built-in.
