In its easiest kind like this:john.doe@domain!.?.! currently, the atoms can consist of 1. alpha-numeric characters 2. Some of these
characters!$&amp;amp;amp;amp;amp; *-= \ ^'| ~ #% &amp;amp;amp;amp;amp; lsquo;+/? _ 3. singular or double quotes as well as any personality inside the quotes Now, to the domain component. A lot of email validation checks thinks that the leading amount domain may

MUSEUM.travel,. global or even.verm&amp;amp;amp;amp;amp;ouml;gensberatung As an example all the following email addresses hold: あいうえお @a. long.domain.example.university one. &amp;amp;amp;amp;amp; ldquo; more \ long&amp;amp;amp;amp;amp;rdquo;@example.website.place!.?.! email@example.com!.?.!
