Whenever I’m composing a new message in Mail and I add an attachment, it puts the attachment right into the middle of the text that I’m typing. How can I force the attachment to go to the end of the message?

This outgoing email has 6 attachments, all conveniently displayed as icons.
Mail will always try to display your attachments directly in your message wherever the cursor is currently blinking, making it difficult to prevent your attachments from cluttering up the text you’re typing.
In Mac OS 10.5 Leopard, a new feature forces Mail to insert your attachments at the end of your text. You can turn this feature on by choosing Edit > Attachments > Always Insert Attachments At End Of Message.

Mail Attachments Iconizer lets you work more easily with attachments in Mail.
However, even after turning that feature on, your attachments are still displayed inline in your message, which can be a drag since Mail slows down tremendously as it renders large attachments. A Mail plug-in called Mail Attachments Iconizer ($14.99, www.lokiware.info) gives you more control over how attachments are handled. You can choose which types and sizes of attachments should be displayed directly in your emails, which ones should be displayed as icons, and more.
