In early September, I posted about a survey being done by Jan Schaumann regarding how sysadmins viewed their ethical obligations with regard to users. The results of this have now been published by Jan. He’s also shared his talk and slides on the data.
Well worth a look through the data. I took a quick run through of his talk and it looked interesting and is definitely going on my to-read list.
Last week I posted some deliverability advice for the DNC based on their acquisition of President Obama’s 2012 campaign database. Paul asked a question on that post that I think is worth some attention.
Read MoreHow do you contact an ISP about a block that doesn’t have a postmaster page? While there’s no one answer, I do have some suggestions.
Start by contacting the postmaster@ or abuse@ addresses. For smaller ISPs, the same people handling outbound abuse are the people handling inbound filtering.
When you contact them have the following:
Earlier this month Google announced a new set of tools for senders at their Postmaster Tools site. To get into the site you need to login to Google, but they also have a handy support page that doesn’t require a login for folks who want to see what the page is about.
We did register, but don’t send enough mail to get any data back from Google. However, the nice folks at SendGrid were kind enough to share their experiences with me and show me what the site looked like with real data, when I spoke at their recent customer meeting.
Who can register?
Anyone can register for Google Postmaster tools. All you need is the domain authenticated by DKIM (the d= value) or by SPF (the Return Path value).
Who can see data?
Google is only sharing data with trusted domains and only if a minimum volume is sent from those domains. They don’t describe what a trusted domain is, but I expect the criteria include a domain with some history (no brand new domains) and a reasonable track record (some or all of the mail is good).
For ESPs who want to monitor all the mail they send, every mail needs to be signed with a common d= domain. Individual customers that want their own d= can do so. These customers can register for their own access to just their mail.
ESPs that want to do this need to sign with the common key first, and then with the customer’s more selective key.
How does it work?
Google collects data from DKIM and/or SPF authenticated mail, aggregates it and presents it to a Google user that has authenticated the domain.
How do I authenticate?
