How can I validate an email address using a regular expression?

Over time I've slowly advanced a ordinary expression that validates most electronic mail addresses successfully, assuming they do not use an IP deal with as the server component.

I take advantage of it in several personal home page programs, and it works most of the time. But, occasionally I get contacted via someone that is having hassle with a domain that uses it, and I end up having to make a few adjustment (maximum recently I realized that I wasn't allowing four-man or woman TLDS).

What's the great normal expression you have or have seen for validating emails?

I have seen numerous answers that use capabilities that use several shorter expressions, however I would as an alternative have one long complex expression in a easy characteristic in place of several brief expression in a extra complicated feature.
