I am looking for a fix to a problem that I am having with the native Mail App on my MacBook Pro, running OSX 10.11.1.
Since upgrading to El Capitan, the Mail App won't save or remember the outgoing SMTP Settings. Every time I restart Mail, I need to go into preferences and re setup the outgoing Mail server information before any mail can be sent.
I've no idea why this is happening.
I have confirmed all my settings with my ISP, and once setup, Mail works fine. I have even had my ISP log into my system, check the settings and confirm that it is not their issue.
So, does anyone have any idea what can be done about Mail forgetting SMTP settings on closure? Any help appreciated.
