Absolutely yes.

As far as SMTP is concerned, you just provide it with the appropriate headers (the rfc822 is out of date, but is a good start) and then the message body, which can be anything.

You probably want to create a message body that is a MIME encoded message describing the text of the email and any attachments.

The question you should be asking is:

How do I construct a MIME encoded email message that I can send to SMTP?

Also, the problem of creating email messages and sending them has been solved so many times, you should really consider using a library if you're at all able to.
