Zimbra rocks! I hope it will help me shut down some exchange servers .
I've installed the open source version first and the network version later (4.5.5) into an i386 ubuntu 6.06 chroot of an amd64 ubuntu 7.04 clean installation. The install process went smoothly, and afterwards all the services were up.
The two exchange migration tools both import all the messages from a test exchange server running in a vmware VM on the same box, but while all the text is okay, every attachment is munged.
The server logs show only a correct message addition:
mailbox - Added message id=296 digest=Gu15iqTsQd5Lu73szytjMplfuYg= mailbox=3 rcpt=:API:
It is a known issue? Where I should start in order to debug it? Attached example raw messages and decoded images.
