I have a problem getting SMTP to work with an ASP.NET app I have (the error I get is "Cannot get IIS pickup directory"). The app delivers the mail to SMTP using the pickup directory.
I already know what causes the error, it's a permissions problem accessing the SMTP settings (see this link http://www.laptev.com/?p=3). I use a custom windows user for that app which seemingly doesn't have the permissions to access the SMTP settings, when I use the NetworkService account, everything works fine but when I use my custom user, I get the error. Now I'm trying to figure out where the SMTP settings are saved in Windows2008/IIS7 to give the needed permissions to my custom user.
