I add some words in keyword filter, but it seems not working.
I send a mail with a world in subject that I expect to be rejected, instead it is regularly forwarded. Thank you for any suggestion |

Please post the entries you are adding to the keyword file, along with
the original source of the email so we can try to help. Please note
that Microsoft Outlook and a few other email clients will drastically
change the email's content/format when they display it on screen, while
SpamFilter will perform text searches in the original's email source.

These are some words in my keyword filter
(\bsex\b) (\bc[\s-_.]*i[\s-_.]*a[\s-_.]*l[\s-_.]*i[\s-_.]*s[\s-_.]*\b) ((?i)(\bcialis\b)|(\bc.i.a.l.i.s\b)) ((?i)(you[\s-_.]*visit[\s-_.]*illegal[\s-_.]*websites)) the first expression works rejecting the word sex the second one block cialis and some variants (c.i_a-l i s, etc) I found the third in the forum, and it should work as the second, but it doesn't I wrote the 4th to reject a full sentence occurrence: it doesn't. |

I learned to add 'Subject' to make SF find keywords in the mail subject:
(\bSubject:\b \bcialis\b) will find the word cialis only if it's in the mail subject while (\bcialis\b) will find cialis only if it is in the mail body, won't if only in subject Is this the right way? |

Another thing that you need to take in consideration is that spammers
also utilize unicode to get past filters. MS Outlook may show you a
subject line with the word sex in it, but viewing the message header
may show that the entire subject is in unicode format. You are on
the right path with prefixing your regex with 'subject:' that will give
you a better chance to match what you are trying to block.

hi Im facing the same problem. I do have prefixed "Subject" before those words, but mostly its not working. even the simple straight words are not filtering, and in some cases, it just prefix SPAM in the subject line and send that mail. So please do help me, what should i do now. Raja Raheel |

Be sure that the subject you are referring to is the one that is read
from the headers and not the subject line you see when viewing the
email in apps such as MS Outlook. The email header information is
where the regex matches against and this is where you may find your
issue at. When I configure regexes to filter on, I always copy
the email header info in full and test against that for subject filter.
