Mail::Sender, attachments and html together

Do you have a question? Post it now! No Registration Necessary.  Now with pictures!

I'm developing a program that send mails with the content in html and
also should send attachments.
I am using Mail::Sender and I can do both things, but not at the same
time :( .
The problem is that with methods like Open and OpenMultipart the
Attach and SendFile don't seem to work. I can send attachments with
MailFile, it is  pretty easy, but I can't find the way to send the
email content as html, I have tried with cctype, headers and also
printing "Content-type: html/text" into the first line of the message
but still have plain text.
Does anyone know how to solve this, any examples would be very useful.
Thanks in advance,
