Dusan, I'm not sure this is an UA issue. At least, not at face value. I'm not expert, but I would ask: Is the email 'me@michele.irish' a workable email address? I.e. does a MX record exist for Michele.irish and does the mail server approve or reject a query to the recipient address (i.e. 'me')? These online tools: http://www.verifyemailaddress.org/ and http://mailtester.com/testmail.php found that the e-mail address 'me@michele.irish' did not exist or was not responsive at the time of validation, therefore, while the syntax may be correct, 'me@michele.irish' was not a valid mailbox . Of course, I'm making this statement using just two test cases, but you get the idea. Here is the sample response from verifyemailaddres.org: MX record found: siracusa.mneylon.com (Priority 30) Connecting to siracusa.mneylon.com Connected to siracusa.mneylon.com Dialog with siracusa.mneylon.com ok ------------------------------------------------------------ 220 mailserver1.blacknight.ie ESMTP Postfix (Ubuntu) HELO verifyemailaddress.org 250 mailserver1.blacknight.ie MAIL FROM: <noreply@verifyemailaddress.org> 250 2.1.0 Ok RCPT TO: <me@michele.irish> 450 4.7.1 <me@michele.irish>: Recipient address rejected: Policy Rejection- Please try later.
