Disabling SSL < TLS in Dovecot and Postfix

Since many of you probably haven’t:

postfix/main.cf

smtpd_tls_mandatory_protocols = !SSLv2, !SSLv3
smtpd_tls_protocols = !SSLv2, !SSLv3
smtp_tls_mandatory_protocols = !SSLv2, !SSLv3
smtp_tls_protocols = !SSLv2, !SSLv3
smtpd_tls_exclude_ciphers =  aNULL, DES, 3DES, MD5, DES+MD5, RC4, eNULL, LOW, EXP, PSK, SRP, DSS

dovecot/conf.d/10-ssl.conf

ssl_protocols = !SSLv2 !SSLv3
ssl_cipher_list = ALL:!LOW:!SSLv2:!SSLv3:!EXP:!aNULL
