I have users who are using the webmail client from home. However, many of them send email from the web client to others in the company and those emails get filed to JUNK.
We run ZCS 7.0 here.
Here's the SPAM test results of an example email.
X-Spam-Status: Yes, score=3.62 tagged_above=-10 required=1
tests=[BAYES_00=-1.9, HTML_MESSAGE=0.001, RCVD_IN_PBL3.335,
Our SPAM filter is set to 1 and we whitelist aggressively. This has been great at capturing SPAM but I am confused why our webmail is getting tagged as SPAM. RCVD_IN_PBL is the culprit but SpamHaus' PBL does not have us listed at all. Why is this so high and how can I fix that?
