ok, i fixed it the stupid way. i edited the file in /var/spool/mail removing the bad emails manually. after looking at them, they're spam. so it's just some spammer. but it also works as a kind of DoS because when i fetchmail, processing one such email takes a long time, it never gets delivered, and the next time fetchmail runs, it tries to load that same email again, taking just as long as the first time :). tiger -- Gerald Timothy Quimpo gquimpo*hotmail.com tiger*sni*ph http://bopolissimus.sni.ph Public Key: "gpg --keyserver pgp.mit.edu --recv-keys 672F4C78" Brahma said: Well, after hearing ten thousand explanations, a fool is no wiser.
