[exim-dev] Enable enable_prdr by default

Hello,

I subscribed to exim-dev, but somehow I have not received this message

https://lists.exim.org/lurker/message/20190112.210337.b527c995.en.html

nor I see in the archives my second message about Meta1.

Anyway, implementing Sieve’s ereject will make it very easy to do rejecting per recipient without explicit ACLs. Just
let the user upload Sieve.

Regards
Дилян
