If you’re having some trouble with Apples latest version of Mail in OS X Yosemite.
You may be in for a fit of anger. I know I was.
Apple in it’s latest attempt to make the OS X Mail Client completely unbearable has decided that it needs to automagically set email settings for you. Except it makes crazy stupid assumptions and keeps resetting *your* manual settings without telling you.
It took me a while to figure this out. But there are 2 easy checkboxes to disable this dumb behaviour and give you back some freedom over what Mail does.
Uncheck both. Re-do your settings as you want. Save and restart the client.
Why? Since Apple knows *nothing* about your hosting providers servers it can’t possibly guess the right settings with any accuracy. That’s basic logic. And I wonder what genius (yes!) thought this kind of feature would make sense in any way.
But yes, it’s on by default. And yes it keeps screwing up your settings for no apparent reason.
My main account would try to use a MD5-Challenge response instead of a proper password. And since my servers do not yet use SSL for email and Apple kind of insists on using it it kept enabling SSL for me. How kind. Fuck off!
Update: If you do not have the issues described in this post but stuff still isn’t working, check out my other trouble shooting post for some more general tips on email settings, preferred setups and security.
