[arch-general] "You have mail" message at login

Whenever I log in to a TTY, I get this message. I read my system mails through mutt, so i don't need this. I have unset MAILCHECK in .bashrc, but no effect. I set MAIL_CHECK_ENAB to no in login.defs, but still no effect. Lastly i tried creating a .hushlogin file in the user's home, but even that didn't have any effect. The message only appears when logging in through a TTY though, not in any other terminal. Any idea what's causing it to show up? ps: Gaetan, here's the content of my .bash_profile [[ -f ~/.bashrc ]] && . ~/.bashrc so, i believe .bashrc is sourced on login.
