I'm definitely going to be testing this on my own server. I've been looking forward to this since it was annouced.

One bit of constructive critism: You got to lose the Mailpile font (which looks like some bastarization of Museo). I know it's part of your branding, but it has no place in the UI. Not only is it much less readable than almost any simpler sans-serif, but the huge x-width makes the text take up so much more space than it needs. Your backup Helvetica Neue with the weight toned down to 400/500 is a huge improvement alone.

Keep up the good work! This is a true service to society.

Brenann (Mailpile designer) here. Thanks for the note and feedback. Good eye- it is a reworking of Museo (due to their license being non compatible with GPL/Apache). Our font is still being developed, the x-width & kerning are far from done and on our radar. After the font is fully done, if the spacing still irks enough people (and ourselves) we'll revisit how and where we're using it! :)
