sendmail: smtp auth: Deferred: Temporary AUTH failure

If I try to use sendmail as a smtp auth client I got the error:

Deferred: Temporary AUTH failure

in syslog see the lines:

Mar 27 10:52:50 newton sm-mta[10041]: [ID 702911 mail.info] STARTTLS=client, relay=mail.example.de., version=TLSv1/SSLv3, verify=FAIL, cipher=RC4-MD5, bits=128/128
Mar 27 10:52:50 newton sm-mta[10041]: [ID 801593 mail.notice] s2R9qoUO010041: AUTH=client, available mechanisms do not fulfill requirements

What is the reason?

sendmail can use SASL2 but for successful encryption SASL needs the libraryies of the CSWsasl package. Add the package sasl and it works!

# pkgutil -i sasl
