Stuart,
Greylisting occurs before the sender has a chance to send the authentication request, so it not going to be possible to allow SMTP Auth to bypass the greylisting process. If you know the IP ranges used by the iPhone user you can manually exclude subnets from being tested for greylisting, but that may not be a practical solution for all iPhone users.
It is possible to install multiple instances of SpamFilter on the same server. First of all, you'll need a separate SpamFilter directory for each instance of SpamFilter you want to run. SpamFilter installs very cleanly, so besides a full install, you could also make a copy of your primary /Program Files/SpamFilter directory and paste it as a separate name, for ex. "/Program Files/SpamFilter2". You will need to modify the new SpamFilter.ini file (and if using SpamFilter ISP "standard" the \SpamFilter\Domains\SFI\Filters.ini file) to adjust the various entries that have pathnames to reflect the new folder for your new installation. You can then run SpamFilter from that second directory concurrently to your primary SpamFilter in the 1st directory.You only need to make sure that the listening IP:port combination is different between the different instances, as SpamFilter cannot listen on a socket (IP/port combination) that is used by a different application. So you should either manually edit the SpamFilter.ini file to change the listening IP, or run one copy of SpamFilter at a time while you change the settings.
If you wish to install additional SpamFilter services, after following the above steps to copy the SpamFilter directories, you can use the INSTSRV.EXE utility from the NT Resource Kits:
instsrv SpamFilter2 "C:\Program Files\SpamFilter2\SpamFilterSvc.exe"
This creates the new service SpamFIlter2. You will then need to go to edit the Windows registry to modify the startup line:
Go to HKLM\SYSTEM\CurrentControlSet\Services\SpamFilter2 and edit the ImagePath key
Add the following startup parameter at the end of it
/startedbyscm:F9D641D8-40E26D57-SpamFilter
So the entry will look something like this:
C:\Program Files\SpamFilter2\SpamFilterSvc.exe /startedbyscm:F9D641D8-40E26D57-SpamFilter
You will now have 2 independent SpamFilter services. You can create as many as you wish...Please let us know if there are any more questions!
