Thanks!
Perhaps you would consider linking to them on your web site ?
I may have been overly harsh,
Yes, you were :)
Open Source software is, a lot of the time, provided out of the good of
peoples' hearts. You should be thankful that someone has gone to the
effort to code something, and released it free of charge. Go ask
Microsoft for the source code for Exchange...
but I hardly ever see open source projects that have all the exterior
hallmarks of being a commercial enterprise.
That's the joy of Open Source software, you don't need to be a big
commercial enterprise to contribute or be successful.
However, it is important to include, or offer source code though for
other GPL applications being included. But no reason to flame (unless he
refused of course, which he didn't).
Anyways, this project looks interesting, and anything that can help get
Postfix out there and replace some of the experience terrible mail
servers out there.
