Hello, we are getting hit pretty hard with SPAM that have spoofed sender headers. This is causing AWL to adjust with a high negative score, which is putting this below the spam threshold.
I see from past posts, that SPF is the 'preferred' method of dealing with this. We aren't huge fans of SPF, and don't want to implement it. Does anyone else have suggestions or things they have implemented to stop the sender forgery? Or adjustments to AWL, or SA?
Here is what a false-negative spam score is looking like from spoofed sender:
X-Spam-Status: No, score=2.41 tagged_above=-10 required=3.4 tests=[AWL=-6.431,
BAYES_95=3, LONGWORDS=1.803, RCVD_IN_PBL=0.905, RCVD_IN_XBL=3.033,
Thanks for the help.
