I found Interworx after spending too much time working on my own solution. Now that I have found you, I am going to migrate.
I only have one question, why not Cyrus Imapd over Vpopmail/Courier?
It has one major feature that the rest don’t… Sieve!
While I am going to make the move from FreeBSD and my current comfort zone, I must say that I am going to miss Cyrus and Sieve.
