At least according to Dave Shea it is:too much spam, and no effective way to deal with it.
The spam has started to flood in recently for me too, and Dave’s post gave me the kick up the jacksy I needed. I’ve dediced to trial Google Hosted Services.
Unbelievable but true, I hadn’t actually used Googlemail before and needless to say I’m *very* impressed with the interface. Google calendar let’s me import my iCal calendars, brill. All I need to find out is if Googlemail will also let me download my email into Mail app, imap or pop, don’t really mind.
