SORBS is very good at detecting stale lists, typo domains, and ... abusers using your service. I'd prefer to not use it as a block, but certainly an advice for filtering.
If you're the only one using an IP that got listed in SORBS, you need to seriously rethink how often you are mailing your customers, your bounce processing, and ... where you originally got those addresses in the first place. And if your system can be driven to generate Backscatter, sooner or later, a Bad Person will cause your IP(s) to be listed. > sorbs is not always a consistent organization, both listing and delisting > can be chaotic, i don't think they have a policy based system, it has in > the past been based on reporting that is vetted only sporadically, you'd > think mozilla would only use dnsbl from larger organisations with a policy > > but it's a fair point to use another smtp host, if hosts in the same > subnet are being abusive, if its cheap high density hosting you might > literally be sharing a name based host ip with a spammer, or you are the > only one NOT a spammer.. my 2c > > in particular sorbs dont seem able to say why you were listed, so you can > stop it happening again, more professional orgs track the cause so you can > fix the problem, maybe you are coming from an ip range that has a spf > record that says mail is not expected ? they should be able to tell you > why, or whitelist your ip, other than a broad statement about blocking a > whole subnet which as high density hosting, is of course going to be of a > high spam potentiality > >> On 17 Jun 2016, at 11:10 PM, Tanstaafl <tansta...@libertytrek.org> >> wrote: >> >> Hello, >> >> I've been experiencing and on/off again problem with my shared dreamhost >> account IP block getting listed by SORBS. >> >> The only reason I know this is because apparently the Mozilla list >> maintainers have configured all of the Mozilla discussion lists to >> outright BLOCK based on being listed by dnsbl.sorbs.net. >> >> After querying where/how to request this be changed through the proper >> channels, I opened a bug with respect to the list infra owners, and >> explained to the best of my ability why outright blocking based on SORBS >> listing is bad: >> >> https://bugzilla.mozilla.org/show_bug.cgi?id=1280451 >> >> It was immediately closed with this response: >> >> "SORBS is an RBL service we use, and generally when you get listed its >> actually for a reason and usually we push back and have the ISP to >> request a delisting since you are placed on this list for a reason. >> Looks like what you are sending is from a dreamhost IP range, are you >> sending directly from a host?
