I spent 4 hours last night with the standard Mac mail trying to get it configured. I had it configured years ago and now it just fails to access pop settings at zoho even though everything is configured correctly. I also find it very funky how mail can be sent but it can take a really long time to access the mail or just disconnect from an account and ask me for my password again.
So I am wondering if anyone here has found a great mail program to replace Mac mail. I saw Mailbird, but that is only for Windows.
