No, it doesn't appear to be a auto-response but again I don't know which post you are talking about if it was anything other than a screenshot it could be a innocent typo.
I looked at the email to nodummy and I didn't see a misspelling unless I am missing something. I really don't believe that nodummy would doctor a email - she doesn't seem to be that interested in SRGE and she seems to take DD seriously and it would damage her credibility to not just present facts.
