We don't use it, but some departments in the school use it and it is useless to tell Lotus users what they should do -- those junk emails are sent out automatically by something, who knows who sends them out. It is Lotus's bug, but so far the Lotus Notes admins in the school have not been able to figure it out what happended, why, and how to fix it. That is why I want to protect my users. I tested your suggestion -- thanks for that! By these testing, I found a new point that can explain all of my above tests! That is: the procmail has a limit to the length of the subject line!!! It counts only the first about 55 characters! Subject:.*is out of works for all cases, Re:, or [Fwd:, but Subject:.*is out of the does not work at all. Then, I try to delete some letters in the middle of the subject line -- As I said that the subject line has a long part Aaaaaaaa Bbbbb/Ccccc Dddddddd/Eeee Ffffffffffffffffff is out of the office If I delete some dddd ffff etc. to make it shorter, then any of my procmail lines work well no matter it has Re: or [Fwd:, or others. The matching string "is out of the office" is at the end of the subject line. So, if it is too long (I counted, if longer than about 55 chars), then procmail could not match the string, and the email goes to inbox. Once I deleted some letters in the middle, it matches and functions. The Re: or [Fwd: just makes it "too long". Strange, but it is procmail's limit. Thanks! Hongwei
