Hello everyone,
I am looking for a milter script (mail filter) that would classify
emails automatically. Something in Perl, for instance.
The purpose is not to fight spam, but to classify emails and ideally
differentiate commercial emails from private or business emails.
After execution, the email would contain an additional header, for
instance X-Email-Type, with some predefined values, like 'commercial',
'business', 'private', etc. Finally, when the filter would not been able
to recognise the content, a special value 'unknown' may be used.
A database maybe used to classify the emails, as well as using
'In-Reply-To' or 'References' to check the validity of the emails.
Also, I would like to retrain the system by reading the content of a
maildir.
Can you tell me if such a filter / service is already existing?
If not, I should be able to write a filter in Perl. Can anyone tell me
if perl performances are good enough for that, or should I start
something in a compiled language?
Thanks.
André
