* - "Becker, Ralf <rb@egroupware.org>" (contains comma outside " or ' enclosed block)
|
||
|
|
* - "Becker < Ralf <rb@egroupware.org>" (contains < ----------- " ---------------)
|
||
|
|
*
|
||
|
|
* About umlaut or IDN domains: we currently only allow German umlauts in domain part!
|
||
|
|
* We forbid all non-ascii chars in local part, as Horde does not yet support SMTPUTF8 extension (rfc6531)
|
||
|
|
* and we get a "SMTP server does not support internationalized header data" error otherwise.
|
||
|
|
*
|
||
|
|
* Using \042 instead of " to NOT stall minifyer!
|
||
|
|
*
|
||
|
|
* Similar, but not identical, preg is in Etemplate\Widget\Url PHP class!
|
||
|
|
* We can not use "(?<![.\s])", used to check that name-part does not end in
|
||
|
|
* a dot or white-space. The expression is valid in recent Chrome, but fails
|
||
|
|
* eg. in Safari 11.0 or node.js 4.8.3 and therefore grunt uglify!
|
||
|
|
* Server-side will fail in that case because it uses the full regexp.
