SASL Auth not working
I did not have this issue with M1, now with M2 I am receiving authentication failures when attempting to send mail with sasl authentication.
i've tried it with and without the -r in the saslauthd command in zmsaslauthctl; stopping and starting that service each time.
this wil probably be helpful:

Nov 22 12:22:54 mail saslauthd: auth_zimbra: firstname.lastname@example.org auth failed: curl_easy_perform: error(7):
