I've been using Mac Mail for years now. My accounts are all currently set up as IMAP accounts but I didn't do that until the iPhone came out, so everything prior was handled as POP. I've got tons of email that I can't just delete because it helps me with referenceing my business history. My web site hosting company only allows so much email storage before I have to pay a ridiculous amount of money and I'm tired of trying to go through old emails to make more space for new ones. Is there a good way for me to save the emails from before a certain date as an archive on my machine (that Mac's Mail app will still search through when I'm trying to look up history) so that I can just delete what exists out on the server? Thanks for your help in advance!
