I have a problem when trying to send out campaigns.
I can send the test emails from the template pages and they get delivered to my inbox. But when I try to send a campaign, I get the following errors for each email:
Expected response code 250 but got code "421", with message "421 Unexpected failure, please try later " Log data: ++ Starting Swift_SendmailTransport << 220-ABC.org ESMTP Exim 4.85 #2 Wed, 27 May 2015 23:24:07 +0200 220-We do not authorize the use of this system to transport unsolicited, 220 and/or bulk e-mail. >> HELO www.XYZ.com << 250 ABC.org Hello USER at www.XYZ.com ++ Swift_SendmailTransport started >> MAIL FROM: <bounced@ABC.org> << 250 OK >> RCPT TO: <emailXYZ@hotmail.com> << 250 Accepted >> DATA << 354 Enter message, ending with "." on a line by itself >> . << 421 Unexpected failure, please try later !! Expected response code 250 but got code "421", with message "421 Unexpected failure, please try later "
When I check the mail queue in Web Host Manager the messages are not being sent to the exim spool. It shows zero messages being sent or trying to be sent.
Previously I am using phplist, and it is sending the emails without any problem. In Mailwizz the test emails and the server confirmation emails both go through fine, but not the campaign emails.
