    I ran into a problem after upgrading SASL from 2.1.14 to 2.1.18,
    and the cause seems to be realms. Both sendmail and Cyrus authenticate
    with the same SASL libraries, using sasldb2 for secure methods.
    After the upgrade, some users could not authenticate with SMTP, even
    though they could with IMAP. Cyrus sets the realm in imapd.conf with
    the `servername' keyword. Sendmail has no way to do this. It uses
    the local hostname, which is different from the Cyrus realm. (I'm
    about to fix that by patching sendmail.)

    When a client connects to a server, there are two realms. The server
    has a realm. The client provides a realm. There is a third realm
    associated with the username and password in sasldb2. Do all three
    of these have to match for authentication to succeed? What happens
    if one or more of the realms are missing? Can they be omitted?
    Can there be multiple realms?
