Instead of remembering all those weird email names, what you could do is:

1) Buy domain and attach google apps to it.

2) Switch catch-all email setting in preferences.

3) When register for a service use email like [e-mail] or [e-mail] etc.

And for sites that don't have insufficiently permissive email regex validators, if you have gmail you can just add a '+' and do [e-mail], [e-mail], etc.

Yeah, you could do that as well. I just don't like the idea that someone holds my email address. After reading few stories where Google/Microsoft blocks access to email, I decided to move my email to custom domain. In case of any issues all I have to do is change MX names to new provider to start receiving my mails again.

You can do the +modifier trick with GApps as well.

Yes, but one of the great things about having GApps with your own domain name, is that you are not tied to Google as an email provider, and can easily switch. If you use something like the '+' modifier, then if you switch away you need to switch to someone that supports the same modifier.

So if your goal is to maintain email-provider independence, then relying on provider-specific features like the '+' modifier works against that goal.

For me though, the main reason I don't use it is most sites that I want to use it on reject the '+' in the address as invalid. It happens enough that I don't bother trying anymore.
