Been using PageSender for a long time and it just keeps getting better. Never had any problems. Am using it on a PPC, OS 10.4.9 with Entourage and love the Spam filtering. I used to get several spam faxes a day, you know the type: "Low Mortgage", etc. Calling the 'remove fax' numbers was a waste of time. Now, I only see them once...add them to the spam list and they're gone. Love it!
