I am not able to do it but i think that will be a great idea to have a component of this kind :
If i receive an email with a subject like "This is your Invoice" Or "This is your Invoice John Smith"
the plugin search some of similar in the past x days and if found analyze received from
if received from are similar (server1.mservice.com, server5.mservice.com) is ok
but if server are different and subject similar it look like a virus spreaded in the word and so give score to block it
An idea for a great plugin
Re: An idea for a great plugin
isn't this more or less what DCC does? and razor/pyzor?
Re: An idea for a great plugin
A really good plugin idea would be something like @ 110% spam-proven server sending 5kV PoE over the Internet.
