Hi, I worked with Cyrus Imapd on a SuSE machine. I remember you have to make sure that the saslauthd is actually running. Otherwise there will be nothing that actually listens for passwords and pass them on ;-) So, first step: install all the necessary packages then enable all the daemons you need then add the users and create them some passwords then try if it works. There are A LOT of Cyrus Imap howtos on the web that explain this stuff in detail. :-) have fun, Tobias
