AUTH=client, available mechanisms do not fulfill requirements (CentOS, Sendmail)

Alle Jahre wieder läuft mir dasgleiche sendmail Problem in Verbindung mit Gmail SMTP via Sendmail über den Weg:

/var/log/maillog:

sendmail[7077]: STARTTLS=client, relay=gmail-smtp-msa.l.google.com., version=TLSv1/SSLv3, verify=FAIL, cipher=ECDHE-RSA-AES128-GCM-SHA256, bits=128/128
sendmail[7077]: w1G9b8C0007075: AUTH=client, available mechanisms do not fulfill requirements
sendmail[7077]: AUTH=client, relay=gmail-smtp-msa.l.google.com., temporary failure, connection abort
sendmail[7077]: w1G9b8C0007075: to=<[email protected]>, ctladdr=<[email protected]> (0/0), delay=00:00:00, xdelay=00:00:00, mailer=relay, pri=120307, relay=gmail-smtp-msa.l.google.com. [IPv6:2a00:1450:400c:c04::6c], dsn=4.0.0, stat=Deferred: Temporary AUTH failure

Grund: Die Verschlüsselungsmethoden fehlen. Lösung:

yum install cyrus-sasl*
service saslauthd restart
service sendmail restart

Danke ans CentOS Forum.
