Hello!

The attachments field is hindering progress owing to lack of understanding on my part. I have:

m = Mailer()
...
m.attachments = [full_qualified_report_filename]

But line 115 in the Mailer code, iterates through the characters 'N', 'o', 'n' and 'e' (trapped with FileNotFoundError exception) not the fully_qualified_report_name. Any sample/example on using the Mailer class? Thanks.
