This article was written for Thunderbird but it also applies to the Mozilla Suite.

Thunderbird normally sends attachments inline (as part of the message body), not as real attachments.

Some recipients will see some of your attachments as part of the message body, even if this makes no sense. For example, if you attach a plain text file, then some recipients will not see an attached file. Instead, they will see the contents of the file at the bottom of your message. If the file is encoded data, then some recipients might see garbage at the bottom of your message.

To send attachments as real attachments, set the value of your mail.content_disposition_type preference to 1. You can do this by using Tools -> Options -> Advanced -> General -> Config Editor to change the value, or by editing the optional user.js file and adding:

user_pref("mail.content_disposition_type", 1);

After you make this change, Thunderbird sends all files as attachments. Even if you paste a file into the body of an e-mail, some recipients might see it as a separate attachment.

Sometimes a recipient might configure their e-mail client to display all attachments inline. There is nothing you can do about that other than tell them it's their own fault.
