Mee too I don't know what is much better with DB4. I just tried it and wanted the SRPM to be ready when DB4 comes in. I have expected to see cyrus-sasl 2.x and DB4 in the upcoming RedHat release. Both packages were on rawhide but now it seems they are gone. They are not in skipjack-beta1. Maybe this meens that DB4 is not important for RedHat but what about sasl? Maybe it was too much trouble with sasl2 and that's why they stay with 1.5.24. I hope not because it will make usage of cyrus-imapd 2.x more difficult in future. -Simon > > I am intrigued by the DB4/DB3 change. Why is use of DB4 important for > Cyrus 2.1.x, compared to DB3?
