hello sophistry,
thanks for reply,
1) as I wrote I'm new in CI and in these forums too - I didn't know where must I post this message. I just searched the word "Email" but I didn't get any answer, so the RichMail lib is new for me but it's interesting - I'll see that.
2) yes, I know it's "generally optional", but it's just my experience, most email client can't render correctly the html part of message without it (I have used a self-developed junk-mailer for newsletters, written in Python).
You're right, content-id doesn't need to have $basename, and what is more RFC decribes it must be world-unique, but it's more confortable to use.
thanks again,
airween
