Hello all, I reviewed archived versions of the (b)(1) test procedure and found a note in the revision history on April 24, 2017 that SMTP Test 10, 11 and 13 were removed as test cases in (b)(1) to reduce the burden of Edge Testing. They also note the removal of "Negative test steps SMTP Test 22". I've attached the archived test procedure for your records. This update occurred at v1.9 which begins on pg. 9, but the language is on pg. 10.
Excerpt of the relevant revision history:
"Removed the following test cases to reduce the burden of Edge Testing: XDR MT Test 19, XDR MT Test 48, XDR MT Test 50a and 50b, SMTP MT Test 17, SMTP MT Test 18, SMTP Test 47 and Test 47a, SMTP Test 10, SMTP Test 11, SMTP Test 13. Removed Negative connection test steps SMTP Test 22, documentation of negative authentication due to an invalid DIGEST-MD5 value."
