I can see why folks don’t really run smtp services these days, as the amount of spam is crazy. Once you filter the spam, you then have to contend with all the bounce messages you get from spammers using your email address as a from address.
Our smtp server was running great guns on linode 360 account, and then after a few days I started to get atleast 150+ bounce messages an hour. It was at that moment I decided with the assistance of my wife, that running our own smtp server is just not worth the effort. Infact it’s totally not worth it.
As much as the linode 360 account rocks, I cannot justify having it just for web content. So terminated the service. Moved our weblog over to another location.
