I just did a little survey on my own. My spamfilter is set up in a way that it logs each letter into a logfile (spam and ham both into their own logfiles) and keeps record of some of the emails' properties (From, To, size, matching Spamassassin filters, date, ...). The spamfilter works pretty well: 95% of real spam is identified as spam and only a very small number of emails (let's say 0.1%) is a false positive (where I mean a ham is identified as spam). According to my logs it seems that most of the time only 1/3 of all incoming mails is ham and 2/3 is spam. Around Christmas and New Year's Eve things got a lot worse: 4/5 of all my incoming mail was spam! Thanks to Spamassassin I could still enjoy reading my mail even during Christmas.
