Default it was: "auth_mechanisms = plain login" and I added cram-md5. After restart all work perfectly. But after I added: driver = passwd-file args = scheme=cram-md5 /etc/dovecot/cram-md5.pwd I can't set default lines because I got error. Please tell me which lines should be changed to resolve this issue. Should I remove "login" from auth_mechanism ("login" was default setting and I would like to move back to default settings)?

Because cram-md5 needs the user's password for calculating responses, it cannot work with hashed passwords (one-way encrypted). The only supported password schemes are PLAIN and CRAM-MD5.

Also it clearly does SQL lookup, so that error is happening with SQL passdb. You need to remember to restart dovecot between configuration changes.

Is it possible that hashed password from cram-md5.pwd file was written to database (if yes then where - I have ISPconfig)? I wasn't change any userdb {} block and this second userdb block has this same lines like default settings in passdb block.
Try
auth_debug=yes auth_verbose=yes
and see if it gives any more reasonable messages.
