My mail is not sending or receiving.
I get all accounts whirling away but on the activity pane at the bottom it states that the working rate (incoming mails) is zero. I run 10.7.5 on a 2008 iMac, 2.8 Ghz Intel Core Duo. 4GB 800 Mhz DDr2 SDRAM. My mail accounts work fine on iPad - same settings as on the imac, so I guess there are some background files that have got corrupted? Help!
