Rebuilding

Turns out the datacenter outage this week seriously damaged the host server that my VPS was runnning on. I've spent the better part of the waking hours since I got home last night rebuilding the email server portion.

I swear by Postfix, complimented by policyd-weight and postgrey. I have some tweaking to do to the policyd-weight settings and I need to install fail2ban for the spammers who continually hammer the server in spite of receiving a BuzzOffNotice. Amavis, ClamAV and SpamAssassin are fairly hands off. One site I was reading debated the need for ClamAV these days, saying that most of the virus payloads get stopped by the anti-spam measures. Interesting idea.

It's not lost on me that, yes, I should have had a backup of these files. It's not without irony that I deleted the files from the last server update just last week. I'll have to search the WayBackMachine for a few bits of website that I don't have backups of.

As for things residing in ~, I got sshfs working this afternoon and I'll be able to keep settings synced across different servers. Next step is to combine sshfs with autofs and have it mount the remote files as they are needed.

I'm really loving the theme/design of your site. Do you ever run into any browser compatibility issues? A handful of my blog readers have complained about my blog not working correctly in Explorer but looks great in Opera. Do you have any recommendations to help fix this problem?
