ocean.301south.net is a low-volume mail server. 95% of my logs are spam rejected by postgrey.  The other 5% are evenly divided between spam which gets screened out by SpamAssassin and actual legitimate messages, which probably number 25 a day coming in and fewer than 10 a day going out.   So you can imagine my dismay when Yahoo(!) refused to accept an email from Abbie to her mother on the basis of my server’s reputation.

There’s obviously an element of inferiority-complex here.  In a world where everyone is known by his google ID and it’s all but impossible to acquire a static IP address, I am in the extreme (maybe even six-sigma) minority to be administrating my own e-mail server.  I hold a physical copy of all my emails on my home server (and Abbie’s, too) and I never see ads.

But lately, particularly since moving from a DSL connection to a Cable connection (hosted by Cox Business), I’ve started to notice that emails from my domain were frequently spurned, often winding up in spam folders or being rejected altogether, particularly by Yahoo servers.
