using expressions in antispam filter

Hi, Leo, and welcome to the UTM Community!

Without seeing a sample of what you want to block, it's difficult to be certain, but it sounds more like people getting on mailing lists they want off of, not like spam.

thanks for reply

what are we having here is spam messages with the same subject and content but different domains, i need to use the expression filter but it made a problems for me when it blocked the other legit messages and senders

i need to know can i block words like ...boy, girl because when you do boy on the filter it blocks the word boycott for example

what i need is to block the exact word 

thanks

I've not seen that kind of a problem, but I believe that you can use  boy  with a space in front and behind it.  Does that work?

thanks for your reply 

its a problem because many important emails were blocked when i use the word (fu*k) in the expression filter

many emails were considered a spam for the reason of using this filter (as the log said)

so i want to make sure that the (spaces) will work before applying my execs will get crazy if they will not receive their emails again 

any idea from anyone?

I solved this and its working 100% now, if you want to block specific word you will have to do this expression, for example if you want to block the word "sales" you have to do this: (\bsales\b) 

Thanks, Leo - I didn't know one could use REGEX there!

you are right, its 100% REGEX i was examining expressions in a REGEX notepad and it worked
