I cannot send email (SMTP) from my MacBook OS 10.8.5, email version 6.6
I have checked all the settings and they are exactly the same as my iMac OS 10.5.8, email version 3.6
Email works absolutely fine on iMac (POP and SMTP) but only incoming (POP) works on my MacBook and not the outgoing (SMTP)
I have deleted all email accounts and set them up again, but that hasn't worked. I've tried changing port to 2525.
As I said, all settings are the same as the iMac which works fine.
This is driving me insane, so any help would be most welcomed please.
Change the name of the computer in the Sharing preference pane to one that has no spaces or punctuation marks.
