ISP’s block port 25

After spending a few hours hacking around with the James mail server and qmail trying to figure out why my server hosted at Rackspace was not accepting my smtp traffic from my home SWBell DSL connection, but would from my work’s VPN, I came across this article.

In a nutshell, ISP’s have been blocking all port 25 traffic to stop spammers. I have issues with that, as now I cannot use my own smtp server most of the time. I think the bigger problem is that they did not bother to notify their customers that this was happening.

*sigh*, so many companies don’t seem to understand the importance of great service and support.
