Sendmail doesn't check for valid address's

[Nicolas DS]

Hi,
I would like to do sent a mailing with all address in Bcc and text instead of a destination email.

Like this:

But I see in code that if I put 'Undisclosed recipients' in 'To' field, I gonna have an error because:
In poweremail_core.py
=> def get_ids_from_dict
=> line 233
=> result['all'].extend(ids_as_list)

the result['all'] will contains the 'Undisclosed recipients' text, which is not a valid address and sent trough SMTP.

A final check should be done on all address ONLY in result['all'] that will remove all no valid address from this list.

See attachment for implementation of this method.
