The Boston Diaries

The ongoing saga of a programmer who doesn't live in Boston, nor does he even like Boston, but yet named his weblog/journal “The Boston Diaries.”

Go figure.

How AOL handles their email

A discussion Mark and I were having turned towards email—specifically, sending email to AOL. He's communicating with some people who use AOL and is concerned about his email getting through. He heard that AOL had proposed some new DNS record and was curious if I heard anything about it. I had not, but I started doing a Google search.

Going through the results, I came across a link to the AOL Postmaster Info page, a document that describes how AOL handles email and the criteria they use to accept or reject email. There is some very good information here (for all the ribbing AOL gets from the rest of the Internet, their infrastructure and networking architecture is incredible and they certainly know what they're doing technically, if only to handle the millions of subscribers).

You have my permission to link freely to any entry here. Go ahead, I won't bite. I promise.

The dates are the permanent links to that day's entries (or entry, if there is only one entry). The titles are the permanent links to that entry only. The format for the links are simple: Start with the base link for this site:, then add the date you are interested in, say 2000/08/01, so that would make the final URL:

You can also specify the entire month by leaving off the day portion. You can even select an arbitrary portion of time.

You may also note subtle shading of the links and that's intentional: the “closer” the link is (relative to the page) the “brighter” it appears. It's an experiment in using color shading to denote the distance a link is from here. If you don't notice it, don't worry; it's not all that important.
