If you needed yet another reason to switch from operating your own [MTA](http://en.wikipedia.org/wiki/Message_transfer_agent) for transactional email to using a service provider, [SendGrid](http://www.sendgrid.com) recently introduced a killer feature: [reply processing](http://blog.sendgrid.com/28/why-you-should-not-use-noreplydomain-com-in-your-emails/).  No more need to send emails from “no-reply@thatsoundsrude.com."  Instead, let people take actions simply by replying to emails.  This is a feature that I have absolutely loved about [disqus](http://disqus.com) from day one: being able to reply to comments by replying to the email I get from disqus.  Tons of others should do this.  Accept a friend request?  Just reply "yes” to the notification email.  SendGrid’s reply processing API takes all the hard work out of this.  I can’t wait to find the time to switch [DailyLit](http://www.dailylit.com) over to SendGrid for just that reason.  
  
P.S. If you need yet another reason why you don’t want to operate your own MTA, try squashing the [backscatter](http://en.wikipedia.org/wiki/Backscatter_%28e-mail%29) problem by properly configuring [Postfix](http://www.postfix.org/) (and then realizing that Thunderbird no longer works).  Spent two hours on that this weekend – a total waste of cycles that could be used for creating value for endusers!
