Subject: [Tmail-talk] Obtaining raw header text for "illegal" headers
Message-ID: <DBBFA962-E90D-406A-AF16-939777723DD8@mac.com>


Hi,

I got an email with this From: header:

 >> mail['From']
=> #<TMail::AddressHeader "xxyy at xxyy.zz<xxyy at xxyy.zz>\r\n">
 >> mail.from
=> nil

Now, I would like to read the "xxyy at xxyy.zz<xxyy at xxyy.zz>\r\n" value,  
but how do I do this?

 >> mail['From'].body
=> ""

Is it not possible to access the raw header data if the header is  
illegal?

 >> mail['From'].illegal?
=> true

Thanks,

Morten

Hi!

To write out an attachment you need to fetch the body of the
attachment and write it to a file.

I've written a script using TMail to extract mime attachments and
uuencoded attachments that you could look at to get an idea. :)

This is what I've done to extract the attachments.

If you'd rather develop it in a rails application you could do something
like this.

I created a model to manage the attachments specifically, once I did that
everything was made much easier and cleaner.  I then created a class method
called 'extract_attachment' which had an argument of a tmail mail part.  The
method took the part and extracted and stored the contents and returned it
so that it could be assigned to the email.  View below for the code, hope it
helps.  This could work easily with a file system storage as well, instead
of Attachment.new you would open a new file, dump the contents into it, then
close the file.

Reason for the rescues:
The I found that not all emails were parsed properly with the TMail class
library.  So I had to do quite a bit of trial and error on insertion.  If
there's a better way to do that, please let me know.

# == Schema Information

    part.original_filename.nil? or part.original_filename == '' ?
'Attachment' : part.original_filename
  end

  def self.part_disposition part
    (part.content_disposition.nil? or part.content_disposition == "inline")
? "inline" : "attachment"
  end
  
  def self.part_cid part
    (!part.header_string("Content-ID").nil? and
!part.header_string("Content-ID").empty?) ? part.header_string("Content-ID")
: nil
  end
    
  validates_presence_of :email_id, :filename, :data
end

Hello, TMail-Talk!

I'm a hobbyist Ruby scripter, and I'm just starting to get familiar  
with TMail.

In my quest to find some way to decode attachments encoded in RFC  
822, I found the fresh discussion on http://www.ruby-forum.com/topic/ 
138425.

I have searched all over now ... Is there really no way of decoding  
these attachments in Ruby (in another library, for example)?


Regards,

J?rn St?ylen, Norway.

J?rn,

I wrote a library called MMS2R that operates on top of TMail.  Even
though the name leads one to think its only for mobile MMS messages it
works with any email.  It makes getting at email attachments very
simple.

http://mms2r.rubyforge.org/

Thanks
Mike

Our /tmp directory is filling up with dated ruby_tmail* directories and
files. Is TMail supposed to automatically clean those up after use? Am I not
closing the object properly? Or do I just need to clean them up manually?

Thanks!
