I report all the spam that has got past the filters while I have been at my workstation, which is a big chunk of it. I don't bother with stale stuff that's arrived overnight etc.
The typical SC headers of a message might be:
I assume the problem is partly that SpamAssassin has lots of filters for English spam but fewer/none for foreign language spam.
Just to clarify, all the e-mail shown was 'goof' e-mail:- Correctly identified spam goes to 'held mail', while spam I've had to delete manually goes to 'deleted' (which is what is shown in the screenshot).
Basically the state with the e-mail service is: Users can chose a number of settings for thier mail to be filtered by - including SpamAssassin level and a choice of RBLs, plus a sender blacklist and whitelist. Any mail classified as spam under this system is put in a 'held mail' folder on the server. I use IMAP so the 'held mail' folder on the screenshot holds e-mail identified as spam.
If you're not familar with SpamAssassin, how it works is: Each message starts with a score of 0. Tests are performed ( examples ) and the number incremented by the test weighting every time a test is failed. Users can then pick at what threshold a message should be called spam and treated as such.
For example if a message contains 'v1agra' (weighting +2.5) and the message is 40%-50% HTML obsfucation (weighting +2.6) the final score is 5.1. If the user has chosen 5 as thier SpamAssassin threshold, the message will be classified as spam.
The SpamAssassin filters and weightings are (AFAIK) configurable by the system administrator.
Basically what I'm asking is: Could we have more SpamAssassin tests to cover the spam that's currently getting through the filters, as pictured.
