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.

CMTP, because it's no longer SIMPLE

I give up.

I have no idea how email even works anymore.

One customer keeps sending us notification messages—you know, the ones that have:

**********************************************
**   THIS IS A WARNING MESSAGE ONLY         **
** YOU DO NOT NEED TO RESEND YOUR MESSAGE   **
**********************************************

right in the middle, so of course they can't see it. I have no idea what email client they use (but I'm afraid the answer to that will be Lookout Outlook, or even worse, Lookout, Exploit! Outlook Express), nor how their email client is configured.

I suspect this is related to the server in question being under a heavy system load—Sendmail will stop processing emails when the load gets too high. That much, I'm sure of. What I'm not sure of is if Sendmail stops accepting incoming connections, or does it stop sending out emails as well. Or is that a configuration option?

And how does the <shudder> control panel Insipid fit into all this mess?

And let's not forget that I shoehorned the greylist daemon into this mess (and here I thought I fixed a problem—maybe not? Who the XXXX knows? I certainly don't).

If anyone can troubleshoot this problem (preferably with a large caliber gun), please let me know, okay?

Obligatory Picture

[It's the most wonderful time of the year!]

Obligatory Links

Obligatory Miscellaneous

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: http://boston.conman.org/, then add the date you are interested in, say 2000/08/01, so that would make the final URL:

http://boston.conman.org/2000/08/01

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.

It is assumed that every brand name, slogan, corporate name, symbol, design element, et cetera mentioned in these pages is a protected and/or trademarked entity, the sole property of its owner(s), and acknowledgement of this status is implied.
