How do I keep copies of all messages?

Question

Thius may be an easy one, but I can't figure it out. I have three email accounts: 2 IMAP email accounts and a .Mac account. Since the first two are IMAP, when I delete it on my computer, it gets deleted on the server. If I don't delete them, I very quickly reach my 100 Mb limit (in a few days.) I also like to keep my inbox clean, only active issues.
I could manually save all messages, but that is a chore.
Ideas as to how I could set up a mailbox that keeps a copy of EVERY message (in, out, deleted) on my computer, while allowing me to delete from the servers?
Thanks,
Peter

Answer 1

Open Mail Preferences, select Accounts from the toolbar, select an account. Click on Mailbox Behaviors tab. Last item, Trash: uncheck the box labeled "Store deleted messages on server." This will stop Mail from storing deleted mail on the server. All deleted mail will now be stored locally. Do this for each of your mail accounts, then clear out the deleted mailbox on the server to recover space.
You will note that you can do the same for Drafts, Sent, and Junk mailboxes if you prefer to save them locally rather than on the server.
Why reward points?(Quoted from Discussions Terms of Use.)
The reward system helps to increase community participation. When a community member gives you (or another member) a reward for providing helpful advice or a solution to their question, your accumulated points will increase your status level within the community.
Members may reward you with 5 points if they deem that your reply is helpful and 10 points if you post a solution to their issue. Likewise, when you mark a reply as Helpful or Solved in your own created topic, you will be awarding the respondent with the same point values.
