Who remembers SquirrelMail

@feld I don't want to. But I do.

Skipped IMP/Horde.

Then there was RoundCube.

After came RainLoop which has been maintained in the SnappyMail fork.

... still can't believe a web app can be more performant than Thunderbird - in worse environments too.

@mWare I'm still using roundcube at the moment but need to switch to snappy

@feld you'll never look back. It even lets you sign in to multiple accounts from one login session.
