-----------------------------------
Summary: The email validation routine is incorrect
Key: JSPWIKI-1243
URL: https://issues.apache.org/jira/browse/JSPWIKI-1243
Project: JSPWiki
Issue Type: Bug
Reporter: Alex O'Ree
the current email validation is regex based.
> ^[0-9a-zA-Z-_.+]+@([0-9a-zA-Z-_]+\\.)+[a-zA-Z]+$
which...is fine it will block many legitimate email addresses
there's a lengthy discussion here
[https://stackoverflow.com/questions/201323/how-can-i-validate-an-email-address-using-a-regular-expression]
to fix, we can either use the java api as a "more or less good enough solution"
or turn this into something stupid simple like, it needs at least one
character, followed by the at symbol, followed by at last least one more symbol.
issues with the current setup
* unicode, non-ascii characters, emojis (yes they can be in email addresses)
and i'm not sure but i think ip addresses may fail on this one.
the RFC is very complex and what we have is fine for users with ascii email
addresses but that's a smaller percentage of the global population.
