I’m still in the trial of HEY.com and like it so far.
But I really miss the support for own domains and other things I have from my mailbox.
Therefore I created a project on Github to provide some manuals how to setup your mailbox using some of the ideas if HEY.com.
I just created that in the middle of the night, because I can not sleep.
Feel free to contribute, change or add other mail services.
I really think these ideas of basecamp for HEY need to be shared.
