I am of the understanding that Apple no longer supports connections with older SHA1 type encryption. It still supports TLS 1.2 but with dovecot some versions are limited as to their lack of support for SHA 2. Is anyone at Apple able to shed any light on this subject as it makes sysadmins life a misery to not have documentation from them on this.

Get mcOS Mojave doesn't work. It gives an Error when transferring to system preferences, software update.

I applied immediately have apps in the store and got no response. Why have an application process that just ignores applications, if they are denied why not just inform the developer its basic business etiquette !
