I have various servers with some hundreds of domains and thousands of users running sendmail and im testing qmail-ldap to migrate them.
We use virtualmin(web interface) so each client can administer his own mail users. I discovered qmail, then qmail-ldap, vpopmail, phpQLAdmin and various imap clients. My question is, what do you consider the best configuration for the next needs: -Scalability -Speed -Manageability What imap server would you recommend for speed? Is vpopmail the way to go? Is is reliable? Does it support cluster features? Is vpopmail+ldap well tested? Does qmail-ldap without vpopmail has an interface for administrators of single domains? Is phpqladmin reliable and easy for end users? I'm already migrating our small staff mail server to qmail-ldap and I know the only way to learn is trying, but I want to hear other experiencies. Omar
