domain

Using one Apache Solr search core with more than one Drupal website isn't too difficult; you simply use a module like Apache Solr Multisite Search, or a technique like the one mentioned in Nick Veenhof's post, Let's talk Apache Solr Multisite. This kind of technique can save you time (and even money!) so you can use one Hosted Apache Solr subscription with multiple sites. The only caveat: any site using the solr core could see any other site's content (which shouldn't be a problem if you control all the sites and don't expose private data through solr).

There are two ways to make Apache Solr Search Integration work with Domain Access (one of which works similarly to the methods mentioned above for multisite), and which method you use depends on how your site's content is structured.

I registered isthereamoduleforthat.com on 2010-08-19 for fun—but after three years, and little traffic (besides bots and the occasional Drupal user popping over from an old link), I'm shutting down the site, and will let my domain registration expire.

If someone is interested in the domain, let me know how you'd use it in the comments below, and I'll consider transferring it to you instead of letting it expire and a squatter taking over.

Email is hard. In fact, it's so hard that I probably have five or so blog posts half-written on this blog that I've abandoned simply because I don't think I could distill them down into something worthy of posting (I like being able to explain things understandably or not at all!).

I don't think there's anyone involved in administering a domain name and email who hasn't gotten burned by SPF (TXT) records at least once. Here's a good overview of how to build a proper SPF record for your domain. SPF records are used by many (if not most) ISPs these days to evaluate whether an email is coming from a particular domain or not.

Email providers like Google, Apple, Hotmail, etc. will evaluate every email they receive against your domain name's (example.com) SPF record, and if the email didn't originate from the IP address specified, or doesn't match up to any other SPF parameters, the email will be silently deleted. And this will cause you to pull your hair out.
