[development] Fwd: E-mail attachments

Hi, I keep developing my module, and inside it I am sending e-mail. I am also trying to attach a file, to no avail. I have installed mimemail, I have changed mime type in my code, I have dpm'd everything. dpm gives me correct values, and the subject and body of the e-mail come through, but I couldn't get file attachment to work at all. What else can I do? Regards, PS: You can see the code at http://drupalcode.org/sandbox/Kartagis/1543120.git/blob/da47378:/pass2pdf.mo...
