==Making an email

You can make an new mail object via a block, passing a string, file or direct assignment.

===Making an email via a block

 mail = Mail.new do
      from '[email protected]'
        to '[email protected]'
   subject 'This is a test email'
      body File.read('body.txt')
 end

 mail.to_s #=> "From: [email protected]\r\nTo: you@...

===Making an email via passing a string

 mail = Mail.new("To: [email protected]\r\nSubject: Hello\r\n\r\nHi there!")
 mail.body.to_s #=> 'Hi there!'
 mail.subject   #=> 'Hello'
 mail.to        #=> '[email protected]'

===Making an email from a file

 mail = Mail.read('path/to/file.eml')
 mail.body.to_s #=> 'Hi there!'
 mail.subject   #=> 'Hello'
 mail.to        #=> '[email protected]'

===Making an email via assignment

You can assign values to a mail object via four approaches:

* Message#field_name=(value)
* Message#field_name(value)
* Message#['field_name']=(value)
* Message#[:field_name]=(value)

Examples:

 mail = Mail.new
 mail['from'] = '[email protected]'
 mail[:to]    = '[email protected]'
 mail.subject 'This is a test email'
 mail.body    = 'This is a body'

 mail.to_s #=> "From: [email protected]\r\nTo: you@...
