Regex: account@domain (active directory)

Question

Something like testuser@test.local should be a match. The regex I use is:

\w[\w\.\- ]*$/@/^[a-zA-Z][a-zA-Z0-9\-\.]{0,61}[a-zA-Z]

What did I miss?

It's not like an E-Mail because it can be many sublevels in the domain e.g. test.local.country.city.street

`\w[\w\.\- ]*@[a-zA-Z][a-zA-Z0-9\-\.]{0,61}[a-zA-Z]` would match — Alex Shesterov, Apr 03 '18 at 12:05

Are you sure that complex names and domains of level above second should be considered incorrect? — Gangnus, Apr 03 '18 at 12:10

`$/@/^` can never match. No string has characters after the end of the string (or before the beginning). — melpomene, Apr 03 '18 at 12:24

You should also define, where in the text that address can appear. But if the address is on a separate line, then:

^[\w]+\@[\w]+\.[^\d\W]+$

The test is here.

If you want to accept complex names and domains of level above second, too, then:

^[\w]+(\.[\w]+)*\@[\w]+(\.[\w]+)*\.[^\d\W]+$
