thx for the hint, I will check after work.
I got another mail from them: please excuse our second mail (about the rogue application) it was sent by mistake to you and was not intended for you :-))
I have seen this happen frequently when the guys doing the support know nothing about their job and just skim the support seeking mails for keywords and then select from a database of ready made emails and send them back
Or they really sent me that mail by mistake...
anyway I'l check back later and report what happened
