Is the “professional world” a place where you’re paid for your work? Because I’ve been paid for my work for 35 years, and I’ve never touched or dealt with either of those programs. I’ve used Mutt for about 20 of those, and nobody’s complained about my emails, nor have I had any trouble reading others’. As other replies to you have pointed out, your particular experience is not definitive of the standards of some “professional world”. In fact, from your description, it sounds like you’ve been working in some pretty unprofessional places.
