Description Dirk Ahrnke

2021-02-02 17:03:18 CET

Template /etc/univention/templates/files/etc/postfix/main.cf.d/60_tls will exclude SSLv2 for unset mail/postfix*tls*protocols. 
At some stage SSLv3 was disabled, most likely by settung UCRVs.

Using TLSv1 and TLSv1.1 is not recommended for some time, we should disable these protocols by default. ("!SSLv2, !SSLv3, !TLSv1, !TLSv1.1")
