Redirecting SMTP

Due to my new appartement I have a new ISP, like all of them reroutes every connection on port 25 to it’s own smtp server. This is fine if you use their e-mail service but not if you are a domain owner or small company that just wants to use it’s own mail server. Today I fixed this issue in 10 minutes using rinetd on a server of mine, it redirects tcp traffic from one port to another, bypassing port 25 until I’m past my isp network.

Spammer makes me laugh

I had some interesting spam messages today. Well not interesting enough to leave them on my site but in their mark-up. Every single link had the attribute rel=”nofollow” defeating the biggest goal the spammer is after, link credit. The only thing he accomplished was me reading the comment and give me a laugh.
