I've seen responses from Dan and Adam so far, and got confused when I saw a reference in Dan's response to one from Sean -- which I haven't seen. So I checked the MUUG Roundtable archive on the MUUG website, and sure enough, there's one from Sean and Brian!
Does anyone have any theories why the other two responses didn't get to my inbox? And yes, I checked my Spam folder; they aren't there.
I think we're getting closer to solving this... I run my own mail server and have complete control. I don't use RBLs. There is no chance of "lost" mail or false-uncrecoverable positives.
Anyhow, the long Sean reply was "missing" on mine too but I checked and it was in my "possible spam" inbox with a .5 spamminess score (exactly the cutoff I use). Anyhow, if it got labelled as spammy by my spambayes, then I'd be willing to be providers out there (gmail) might be just throwing messages like that away.
Next time this happens (someone mentions a missing email), I'll check the spamminess score, and if they are all in the spammy range, then we pretty much know for sure it's over-aggressive mail service providers.
PS The Brian Doob possible missing one got a .13 spamminess in my system, not very spammy, but still not zero. And it had a URL + only 2 other lines added, so aggressive heuristics may decide it is spam.
