Such is noted on the product documentation so how can you complain?
They only support SMTP/POP3 and you don't have such.
I have installed Norton Internet Security 2005 and now I'm having problems with my university encrypted email account. Norton says it is not supported and then I shut the incoming and outgoing verification down (which I didn't like at all). For my surprise it didn't work. I had to disable the privacy protection feature as well. Is it really necessary or I am doing something wrong? I guess it's not reasonable... How can Symantec allow such a thing to happen?
