I found the below solution to fix this issue.

# openssl dhparam -out /etc/pki/tls/certs/dhparams.pem 1024
Add to /etc/mail/ file.

O CipherList=HIGH:!ADH
O DHParameters=/etc/pki/tls/certs/dhparams.pem
O ClientSSLOptions=+SSL_OP_NO_SSLv2 +SSL_OP_NO_SSLv3
# make -C /etc/mail/ and service restart sendmail
