On My Mac is the area where you would store anything that you wished to keep more or less permanently. If your ISP gives you lots of mailbox space, you may not care about this. My ISP gives me limited space per account, so I have rules set up to copy certain messages into folders that I have set up under On My Mac. If and when I delete some of them from the server, I still have local copies.I have been a happy Apple Mail via POP user for years. I have been using SpamSieve for a long time.
About a year ago I moved to using IMAP, so that my iPhone and MacBook Pro were aways in sync. Please could someone help me understand the "On My Mac" mail account? I see this below the list of Smart Mailboxes. It was my understanding that all mail from an IMAP account would remain on the mail server side. What is "On My Mac", and can I remove it? Thanks
I also have mail stored from an account that no longer exists, from my former employer who went out of business.
I have local folders set up for my current business, for mail from friends and family, for transactions, for newsletters, etc.
