recently updated to server version 6.0.8 Network.
Something went wrong with the SPAM control.
If I send email to myself it gets delivered as SPAM. And also from/to certain addresses on our same domain.
This is an example taken from a message header:
X-Spam-Status: Yes, score=6.533 tagged_above=-10 required=5
HTML_SHORT_LINK_IMG_2=0.001, RCVD_IN_PBL=3.335, RCVD_IN_RP_RNBL=1.31,
RCVD_IN_SORBS_DUL=0.001, RDNS_NONE=0.793] autolearn=no
I checked RCVD_IN_PBL and it's related to Spamhaus.
I checked Spamhaus and our server IP is not blacklisted.
Any suggestion on how to fix this?
Any suggestion on how to avoid this every time we upgrade, if it is in any way related to it?
Really appreciate your help.
