My company uses SSL encryption for POP email uses. In 10.2 I had no problem downloading email from the company email server.
In 10.3, Mail.app acts as if there is no unread email, even though by looking at the server using a web (slow) interface, I can see there are many unread emails.
I did not change any settings, I just installed 10.3 over 10.2
I configured Mail on a brand new powerbook as a test, and the same problem occurred, leaving me to suspect it is with Mail.app in general and not the upgrade process
Mail.app 10.3 does successfully download non SSL emails
I have an older computer still running 10.2.8 and with it's 10.2 Mail.app, I can see and download unread emails still --- no it is a 10.3 vs. 10.2 issue
any suggestions appreciated
