Hi all, I'm not sure where the best place to add this question but the General section looked correct. I've got my ISPConfig setup working fairly well just a few more items for me to learn and understand before I finish moving everything to ISPConfig server. However, I ran into one really strange problem that will be a major road block if I cannot solve. Using Postfix and Spamassassin it appeared everything was working fine with my test domains. However, today and yesterday when I logged into my internet account using my dial-up modem I am getting some very strange results. I sent an email from one of my hosted domains to another (both on the same machine) and I get the email marked as spam. This is frustrating because I know it isn't spam but simple a message from myself. The spam list is as follows: 0.9 MSGID_FROM_MTA_ID Message-Id for external message added locally 0.0 HTML_MESSAGE BODY: HTML included in message 2.0 RCVD_IN_SORBS_DUL RBL: SORBS: sent directly from dynamic IP address [18.104.22.168 listed in dnsbl.sorbs.net] 1.8 RCVD_IN_DSBL RBL: Received via a relay in list.dsbl.org [<http://dsbl.org/listing?22.214.171.124>] 1.7 RCVD_IN_NJABL_DUL RBL: NJABL: dialup sender did non-local SMTP [126.96.36.199 listed in combined.njabl.org] Now from my reading on the net about spamassassin the SORBS_DUL and NJABL_DUL are fairly aggressive. This leads me to two options. 1) Should I remove SORBS_DUL, NjABL_DUL, etc. I already use a few rbls before the messages get to spamassassin which was my primary filter on my old server so would these DUL be of use? 2) Did I set something up wrong when installing postfix/spamassassin? Email seems to be working otherwise. Up until this issue I was impressed with the amount of spam spamassassin was filtering. It was really nice to see that I was getting maybe one message come through not marked as spam when it should have. My thoughts are I want to minimize any false positives. Nothing is 100% but sending to myself is extreme. The ISP that I use for dial-up / co-location / high-speed is basically 1 of 2 major ISP in my region so it is not possible to switch ISP's. I assume it is unreasonable to talk to their abuse team and have them maybe talk with these DUL. To generate discussion what are others solutions? If I set the limit to a value like 10 these messages would get through but that doesn't really seem like a nice solution. So thoughts - opinions - options. If it would be helpful I don't mind posting the related information. thx.
