I set-up spamassassin several days before the end of the last year and am very carefully handling mails with it, learning from my old archived spam and such.
Today, my Emacs/Gnus session told me:
nnfolder-save-mail: Buffer exceeds maximum sizeIt is unbelievable, but I have two gigabytes of archived spam/virus mails in about 50 days. This amount does not count with spams that reached non-existent e-mails @janik.cz because I'm archiving the directly on the mail server which is permanently connected to the Internet.
Almost 99.9 percent of spam comes from the world, but I have also identified 5 companies from our country who were sending spams to me. I reported their behavior to their respective trade offices with the help of the template created by local consumer organization.
I think my current setup can be used for about one or two years from now and then, I'll change my e-mail address to different one and will modify my anti-spam rules accordingly.
Update: do you know that 2 GB of spam can be bzip2ed to 40 MB of data?-----
