· Do not use Mail as a storehouse for attached files. When a message appears with an attachment, immediately save the attachment to a separate location on the hard drive if is to be retained. If not, delete it.
· Don’t open an attachment unless you know what it is. If you don’t know who it came from, don’t open it! This is how viruses propagate.
· Don’t open attachments from Apple; Apple won’t be sending you anything like that. The same is true of your ISP. If in doubt, visit the company’s Web page for verification.
· Keep an eye out for attachments in your Sent folder. If you’ve forwarded a message that contains a large attachment, that message and attachment will remain in your Sent folder until you delete it.
· If you can’t open an attachment, drag it to the StuffIt Expander icon in the Applications>StuffIt folder. This utility almost always opens any attachment. You might also drag this utility to the Dock if you use it often.
· Use Mail’s Message>Remove Attachments to send unwanted attachments to the Trash. Periodically review your Sent folder and delete any messages with attachments. If you are pressed for time, look for the messages that have the biggest attachments.
My mantra is delete, delete, delete. Delete e-mail with unwanted attachments from your Sent folder, delete unwanted attachments from folders you’ve created, and finally, delete what’s in the Trash.
Tip: You can sort your messages by file size. Just Control+click the bar that contains the From, Subject, Date, and Received headings and check Size. Click the new heading to sort your e-mail by file size.
