In the process this week of doing a rediculous amount of devlopment work, part of which is migrating my three sites hosting on windows 2003 server with iis6, to windows server 2008 with iis7….
If you are also wondering why as in my case jMail was not happy on iis 7 win2k8, it seems to be because it’s now using the network service account rather than IUSR, so you need to assign the correct execute permissions to the dll that you need to access….
I’n my case, I just granted execute permisson to C:\Program Files\Dimac\w3JMail\jmail.dll to “everyone”… now that machine happily sends emails using that object…
