Cannot send email with any of my accounts on Mail 5.2
I have a Mac Book Pro
Mac Os X 10.7.4
Mail 5.2
I have many diferent email accounts (gmail, hotmail, prodigy.net.mx, etc)
Some are POP, some are IMAP
I have another computer, an iMac with older system and older Mail app. and used same setup for all accounts
I can receive emails, but I cannot send emails on any of the accounts. I have quadruple checked all settings and all seems to be ok.
All smtp connections appear as not connected, yet different servers, or email suppliers, this makes me suspect something else is wrong.
Any ideas? Help would be appreciated.
