I have been running some additional tests on Spamtitan in my lab environment as I am still considering using it for our hosted services environment and interestingly enough came accross a problem when access the Admin Website over SSL in IE, basically I could not generate any PDF files or Download Spreadsheets from the reports and similarly could not download the config Backup.

IE kept throwing the following Error in my face:

Internet Explorer cannot Download topten.php from server myserver.mydomain.com

Thinking this was actually a problem with my Spamtitan, I checked the appliance a friend is using for his own network and guess what, the same issue so I asked him to open a case with Spamtitan Support who came back with the resolution within a couple of hours. (not bad for email support - well done guys)

It would seem that the problem stems from IE itself, they pointed me to the following KB Article: Microsoft KB 323308

I implemented the Registry changes for my version of IE, restarted my Browser ONLY and tried to download the respective items - worked like a charm :)

Hope this is helpful to someone else out there!
