I was using a mail categorising software called Popfile, which uses Bayesian filtering mechanism to categorise your mail. It acts as a POP proxy and sits between your mail client and your mail server. I wanted to use my GMail account with Popfile and found out that I can do that easily with a ssl upgrade to Popfile. I just got that and got my GMail account running with Popfile categorising the mail. GMail automatically filters the spam mail and I can receive only legitimate mail. I can now ditch my old hotpop account, which had 10MB space and 512KB file attachment restrictions.
