I am responsible for setting up and maintaining a mail server for small web-hosting type business. We currently host about 75 domains, around 100 mailboxes and due to the efforts of our sales team, we are wanting to get ready for some great increases in those numbers. I am worried about my current configuration and ease of administration. More importantly (well, at least to the customers) is email deliverability -- it seems that messages delivered to some big players are being marked as SPAM or disappearing altogether. I am asking for insight and advice on 1) if my current choice of software/configuration is a good match for this situation and 2) if there any additional measures I might take to ensure email deliverability?

PostFix: I've done the typical searching around on Google, and I'm not having much luck, I'm setting up a mail server using PostFix, with Courier-Pop, procmail and Spamassassin, and my mail isn't being delivered into $HOME/Maildir. Instead it's going to /var/mail/spool. I'm running Debian Woody and the latest version of everything else. I've double checked every config file I can find but there's something I'm missing...

I installed OS X 10.3.2 from scratch on my Imac and it works great. Then I enabled Postfix using "postfix enabler" and I was receiving email and it was a glorious moment.

However, during my attempts to enable procmail, I broke something and even reverting to the backed up postfix config files won't fix it, nor will re-running postfix enabler.

Can I restore Postfix to its pristine state without reinstalling 10.3, or can I reinstall 10.3 and retain all of the stuff I installed using Fink?

Many thanks. I would ask this question on a newsgroup, but that postfix crew are a bunch of meanies. [more inside]
