thanks for those that replied, sorry for the late reply. In case its
useful to anyone, I can confirm my original code does work, I either
didn't have it in the right place in the config or was confused when
testing this (ie "help" still shows auth option).
Seeing this in the logs for banned "helo"s:
2017-02-17 10:56:08 [16587] SMTP protocol error in "AUTH LOGIN" H=(User)
[94.102.56.181]:12124 I=[x:x:x:x]:25 AUTH command used when not
advertised
