Description

A mail address like "john.doe@☺gmail.com" will return TRUE if passed to GeneralUtility::validEmail(). But if I try to set it as sender or receiver it throws a Swift_RfcComplianceException "Address in mailbox given [john.doe@☺gmail.com] does not comply with RFC 2822, 3.6.2.".

GeneralUtility::validEmail() is actually correct as the smiley in the domain name is valid as long as it's punycode encoded. There's an open bug report/feature request regarding IDN Support for SwiftMailer: https://github.com/swiftmailer/swiftmailer/issues/63

We need to wait on SwiftMailer to fix this.

At the TYPO3camp Munich 2015, we tried to fix this bug and thought that the best solution was to extend the default methods setTo, setFrom etc. in \TYPO3\CMS\Core\Mail\MailMessage\ and execute a IDNA encoding like in GeneralUtility::validEmail:

if (!preg_match('/^[a-z0-9.\\-]*$/i', $domain)) {
    $domain = self::idnaEncode($domain);
}

It seems like the IDNA encoded domain could pass the validation methods of SwiftMailer.

Unlocked after discussion held on TYPO3camp Munich 2015;
\TYPO3\CMS\Core\Mail\MailMessage should be adapted to fix this problem
