My OS X mail has a thumbs up and down botton. It will learn which are junk and not. Takes about a week or 2 but it's good once you get it dialed in.
Command-A to select all, Delete Key. Easy Peasy.
I have a Blackberry Bold that I carry when on call. The e-mail app sucks on that. No way to select messages to delete - you must do it one by one. I wouldn't use BB as the gold standard as it is lacking today.
Cause you can search? Much easier to search on what you are looking for rather than remember where it is in the list.
I thought that was a feature of Mail App in Mountain Lion. Useless for home users. And corporate users typically use Outlook, Lotus Notes, or Groupwise which have that as an option.
Your problem is GoDaddy - crap company. I use HostMonster and it works 100% with IMAP on Apple mail both Desktop and iOS.
A couple things in response. The Apple Mail I'm referring to is the ios version not OS X. I used the desktop version years ago but stopped because it had issues of using GoDaddy POP mail.
And yes GoDaddy was a problem for some time. They used to be really good about 8 years ago and I had to have a domain name for my website/blog. It was cheap at the time and still is, tying the domain name to my squarespace powered blog.
But I'm trying to find a good email host that will work on my ios mail app, or future handsets to upgrade to. Host monster is one idea but I would have to transfer my domain name and open a new account for IMAP unless their POP works well.
I'm using iphone4 because I'm on a special data only plan for deaf and hard of hearing people with a flat monthly rate.
I don't use the Rules preference since its not needed. Maybe in a corporate office setting, that would make sense. But for a freelancer, probably not.
As for BB, I knew many deaf people used it back then on the special data plan and the messenger was fantastic to communicate back and forth with. Was it sluggish? Sure but the last model I had was the Style with a trackpad. Really nice and sturdy build. The keyboard was great as I could feel my way around it as I was trained to "touch type" way back in high school. The best BB I owned before the iPhone 4.
I kind of hoped that Apple would make the phone wider to give more room for their keyboard design, spacing out the keys. But noooo, they had to keep it homogenized.
I have big gamer thumbs. Did they ever take that into account when designing the virtual keys or did they think all men had effeminate fingers? What the-??
Still, I think Microsoft, with the new CEO in the future, may be able to stay competitive. With Gates overseeing the CEO search, they may find the right man or woman.
