AOL’s new IP based reputation monitor
12 years ago
AOL has today launched a new postmaster site. The new site along with its design revamp contains information on best practice guidelines, its whitelisting policy including the three different types of whitelist available, one of which allows guaranteed delivery (goodmail certified mail) and how to join their feedback loop.
For more information on why you should join their feedback loop click here for our previous article on the subject.
In addition to the normal postmaster information listed above AOL has created an IP reputation check tool.
The tool allows anyone to check on their IP reputation as it is measured by AOL. This is a great feature for bulk mailers.
This reputation check allows mailers to see if their RDNS (reverse DNS) has propagated to the AOL servers, one of the basic requirements to send mail to AOL is to have a valid and resolvable rDNS entry, and a 3 color traffic light indicating the status of the IP:
- Green is good
- Yellow is neutral
- Red is poor
- Grey is unknown (AOL have no data)
AOL say that “Mailers should take time to familiarize themselves with this new site, the valuable information contained therein and update their existing bounce codes/classifications with the published ones. AOL’s quote on their new website.” Sound advice.
You can familarize yourself with the new AOL postermaster site here.
Industry Alert: Cox.net launches new postmaster page.
02 years ago
COX.net have launched a new postmaster site.
Lots of ISPs have postmaster pages, but we particually like this one. It’s comprehensive and one of the few that is actually useful to system administrators trouble shooting blocked messages without looking dated on the day it launches like some other major ISP’s postmaster sites.
The Cox postmaster pages provide error code definitions, preferred connection configurations, instructions on how to sign up for Cox’s feedback loop which operates like many others through returnpath. The pages probably won’t give enough information to solve all delivery issues, but they are helpful in getting started and troubleshooting the issues yourself.
Remember, always use the ISP’s postmaster site before sending an email to the ISP’s abuse team, your likely to get a lot better response if you have checked the FAQ’s yourself.

New feedback loop (FBL) from Tucows by returnpath.
02 years ago
Today return path and tucows wholesale division OpenSRS have announced a new feedback loop.
For more information on feedback loops see ‘What are feedback loops (fbl’s) and how can they help my deliverability?‘
Tucows is the third-largest wholesale domain registrar, providing Internet services, through its wholesale division known as OpenSRS, for more than 8 million domains. Tucows hosts millions of email inboxes on its OpenSRS Email Service. This feedback loop will cover all of those inboxes.
For a while now OpenSRS and Returnpath have been offering the feedback loop to limited returnpath customers as a private beta process. Now that the kinks and issues have been ironed out this has been made publically available free of charge to parties sending large amounts of mail to OpenSRS members. The feedback loop (FBL) will forward any mail reported as spam originating from the associated IP addresses back to the listed email address given within the application.
The new feedback loop application is available on the following website. http://fbl.hostedemail.com/

Important information for users of spamassassin.
22 years ago
Recently it has been widely published that bl.open-whois.org, a blocklist which was included within the default install of spamassassin has been taken offline and is no more.
Users of the open source spamassassin application started to report that emails were being marked as spam wrongly. Upon investigation it appears that the domain open-whois.org had fallen into the hands of cyber squatters, presumably because the previous owner of the domain did not reregister the domain.
Although the cyber squatter probably didn’t take on the domain for any malicious reason, it does mean that they have the ability to control the DNS servers for the domain and return results which could cause spamassassin to block and/or bounce inbound emails scanned by spamassassin at worse case, or the best case is that spamassassin will have to do unnecessary lookups to a non-existent blocklist which will cause up to 60 second delays for each inbound email.
As I write this the domain is completely unresponsive to DNS requests and is not returning false positives but Email Manual advice to users of spamassassin would be to reconfigure spamassassin to not check the bl.open-whois.org blocklist to prevent this issue from impacting your inbound email.
This can be done by either upgrading spamassassin to 3.2.x version of spamassassin or by removing any rules which mention bl.open-whois.org from the rules/72_active.cf file within your spamassassin installation folder.
spamassassin 3.2.x is available for download here.
