Mail not sending
Hi all,
I am using Mail on a Mac Pro 2012 with OS 10.8.5. I can receive incoming mail, but sending is extremely slow to none. There is an icon consisting of a circle with a triangle inside and an exclamation mark in the triangle next to the inbox and trash icons. I have run diagnostics and Mail connects to the internet and the Providers SMPT Server . Any suggestion on why I may not be able to send outgoing mail? Thanks in advance for any assistance.
Best,
M.J. Anderson
