sendmail dh key too small

Logjam broke Sendmail?

Generate new DH keys file:

cd /etc/pki/tls/certs
openssl dhparam -out dhparams.pem 2048

Edit sendmail.mc:

define(`confDH_PARAMETERS',`/etc/pki/tls/certs/dhparams.pem')dnl

Update sendmail.cf and restart:

cd /etc/mail
make
service sendmail restart

Refer to https://weakdh.org/sysadmin.html for other service fixes.
