aol goes offline in mail
I useMail on a 2020 iMac running Ventura for two accounts: iCloud and an old Verizon.net e-mail that has since migrated to AOL servers. I would ditch the Verizon account except that it is intimately bound up with my logon ID for banks, shops and a million other things. After the AOL migration, it still works fine on the Mac (I even got to keep the "verizon.net" address) but every once in a while, for no apparent reason, the Verizon/AOL account shows up as "offline" in the sidebar. Clicking the command to go back online has no effect. Unlike older versions, there are few user-defined server settings in Mail these days, and the server names and passwords are correct. The problem usually fixes itself after a few minutes or hours. When I go to the AOL web page to see the inbox, I can see that new messages are there. But it's as if Mail simply can't get online to retrieve them. Any hints to what's causing this?
