I am running mac mail w/ 4 accounts, but only 2 are able to send
I'm having issues with 2 of my 4 accounts (earthlink, mobileme, and 2 work ones that are running through network solutions). The only accounts I'm having issues w/ are the ones going through network solutions. That said, the network solutions webmail is working, just not working from my computer and macmail client. I spent an hour on the phone w/ nework solutions, things are working on their end. I've deleted the account and set it up again, to no avail. Also, I ran the diagnostics and everything says it's working, but it's not... FYI I have a MacBook Pro and am running the latest version of OS X Lion. Any suggestions? Thanks in advance!
MacBook Pro, Mac OS X (10.7.5)
