I’m having difficulty getting Helpspot to submit my username and password correctly in an SMTP authentication sequence when I go to Settings - Email Integration - Outbound Email Test. Do you know if this is a configuration issue on my end?
I’m not sure if Helpspot deliberately omitted my password from this log output below, or if this is actually what it submitted and that’s why it failed. I have tried doing both AUTH LOGIN and AUTH PLAIN manually (in gnutls-cli) and the server accepts them fine.
This is Helpspot 4.5.11 running on PHP 5.6.15 on Windows Server 2008 R2 in IIS.
>> AUTH LOGIN <> c3VwcG9ydEB5b3VyaGVhbHRoaS5jb20uYXU= <> <> RSET <> AUTH PLAIN c3VwcG9ydEB5b3VyaGVhbHRoaS5jb20uYXUAc3VwcG9ydEB5b3VyaGVhbHRoaS5jb20uYXUA << 535 Incorrect authentication data !! Expected response code 235 but got code "535", with message "535 Incorrect authentication data " (code: 535)
