    Mail attachment questions...

    Hi there,

    I've found a script at these great Google fora. a script
    to send emails with attachments.
    The script is below this message, name etc. aren't mine, but from
    the original post.

    My questions are:
    - Is this script extra heavy for a server, or should it be
    no problem?
    - How big do you advise for max size of attachments?
    - Why is the attachment set in an array, when i remove the
    array and only leave it's content-text i get a big time error.
    - Why is this in there? --> $message .= str_replace ("=", "=3D",
    $html_message). "\n";
    - In the source of the mail, there are a few THOUSAND lines of
    the following text. Right after "Content-ID: <image.jpg>"
    "Do1QlNSe3k6Qmp mR0hJTERWWlVhh4 EQABAgQDAggIBwo KBwgCAwABAgMA"
    what is it for? Does it delay my server?


    I'm sorry if this seems kind of lazy from me, but i'm a newb so i
    don't
    know how to figure it out else.


    Thanks in advance & Greetings

      I didn't study the script ... but it should be no problem unless (maybe)
      you have a very large number of users using it.

      0 bytes :-)
      Really!

      Automated mail from the php server should be small and plain.
      In that mail let your users know the URL (by ftp of http) where they can
      download a file.

      Maybe (I didn't look at the code) so that multiple attachs can be sent.
      If you restructure some part of the code you have to know what that
      implies to other parts and change them too.

      That's for the encoding "quoted printable" stuff
      Quoted-printable - Wikipedia

      That appears to be the separation between the different things sent
      within the mail message.
      RFC 2111 - Content-ID and Message-ID Uniform Resource Locators (RFC2111)
      http://www.faqs.org/rfcs/rfc2111.html

      No, it does not delay your server (apart from the building of the
      e-mail)

      Search the web and read, read, read :-)
      Even if not all you find is accurate or up-to-date you will learn a lot
      by reading and trying the things you find in your code.
