I'm in agreement. I don't see an issue. All the largest providers are minimum TLS. 1.2. We have had many years to migrate.

TLS 1.2 has been specified in Aug 2008, so operating systems and software from the last 10 years will most likely support it. I don't see a reason for supporting older versions anymore. There was enough time to upgrade the systems and it got officially deprecated in 2021. -- kind regards Marco Send spam to [email protected] _______________________________________________ mailop mailing list [email protected] https://list.mailop.org/listinfo/mailop
