Email address field email has type character(200)
It can contain multiple e-mail addresses separated by comma.
Applying validation code below removes and does not allow comma separated
address list.

How to modify this so that comma separated address list is allowed ?
How to simplify/improve  this validation, probably some newer root domain
names are not allowed by this validation  ?
