Poisoning Spamtraps

Today’s question comes from Dave in yesterday’s comment section. I wonder if spammers might submit harvested addresses to big-name companies known to not use confirmed opt-in just to poison what they believe might be spamtraps? It’s certainly possible that people submit addresses to forms and big-name companies. But I don’t really think that poisons the […]

Harvesting and forging email addresses

For the contact address on our website, Steve has set up a rotating set of addresses. This is to minimize the amount of spam we have to deal with coming from address harvesters. This has worked quite well. In fact it works so well I didn’t expect that publishing an email address for taking reader […]

MAAWG presents the first J.D. Falk award

Last week at MAAWG went much like all MAAWG conferences go: too much to do, too many interesting panels to attend, too many people to connect and work with, a plethora of very interesting keynote speakers and a total lack of sleep. Most of what happens at MAAWG is not public, but some of the […]

Setting up DNS for sending email

Email – and email filtering – makes a lot of use of DNS, and it’s fairly easy to miss something. Here are a few checklists to help: Data you need before you start: [table] Information,for example Return path / bounce address,bounces.myesp.com Mailserver hostname,mail4.myesp.com Mailserver external address,192.0.2.4 DKIM “d=”,greatbigmarketer.com DKIM selector,oct2012.myesp From / Reply-To domain,greatbigbrand.com [/table] […]

Retrying mail to AOL

I’m working on stuff for MAAWG so I’m really not all that up on what’s happening in the world of email recently. A lot of folks are commenting on my AOL post, and I’m hearing that queues are backing up and emptying as AOL makes changes. One thing people have been asking me is if […]

Canadian anti-spam regulations

Canada passed an anti-spam law in 2010. Implementation of this law (CASL) were initially scheduled to go into effect in 2011. That deadline has passed and it’s not looking good for a 2012 date, either. Canada’s Radio-television and Telecommunications Commission is the agency responsible for enforcement and rulemaking. This week they published 2 bulletins to […]

Can I assume consumer and business filtering is the same?

Today’s question comes from Steve B. I wondered if you know much about hosted email providers such as google apps, Microsoft and yahoo. I have seen a rise in number of people using them to provide their corporate email service.   I am using the same logic that the rules governing delivery to gmail will effect […]

Subject lines

There has been a lot of discussion in various places recently about subject line length and how it affects email marketing. There have been multiple studies done on how the subject line affects opens and clicks. (Mailchimp, Alchemy Worx, Mailer Mailer, Adestra). The discussion has even spilled over into Ken Magill’s newsletter today. I’ve had […]

  • AOL compromise

    Lots of reports today of a security problem at AOL where accounts are sending spam, or are being spoofed in spam runs or something. Details are hazy, but there seems to be quite a bit of noise surrounding this incident. AOL hasn't provided any information as of yet as to what is going on.4 Comments

  • AOL problems

    Lots of people are reporting ongoing (RTR:GE) messages from AOL today.  This indicates the AOL mail servers are having problems and can't accept mail. This has nothing to do with spam, filtering or malicious email. This is simply their servers aren't functioning as well as they should be and so AOL can't accept all the mail thrown at them. These types of blocks resolve themselves. 1 Comment
