long lines in HTML attachments

[Gillou]

Encode your mail body with quoted printable encoding (see doc of module
"quopri"). This way, the recipient's mail client is supposed to re-built the
lines broken by quoted-printable encodings.
I tested this successfully with OE5, Netscape messenger and StarOffice Mail.

Don't forget to add this header to your mail:

"Content-Transfer-Encoding: quoted-printable"

Or download Python 2.2 that has a new "email" standard package that handles
email messages (parse and marshal/serialize) as Python objects (easier to
handle than playing with the various packages you may need for handling
emails).
Heard that this package is available separately and may work with older
Python versions but I have no URL for this (Google for this).
