Mail.eskimo.com should be completely fixed now but I will be replacing it entirely shortly as it is an old server based upon CentOS6, the only one not modernized, and I am preparing a new server to completely replace it which will be based upon the current release of Ubuntu and upgraded as Ubuntu upgrades.

      In the meantime however, I have replaced postfix with the most current version, 3.4.7, as well as openssl with 3.0.0, so all modern encryption protocols should now be supported.
