Hi, I've been tasked with setting up a mail server with Push capabilities. For the most part I think I am onto a winner, however I am having a few issues with Z-Push. It can receive e-mail OK and it works wonderfully, however on trying to send email I have found that if I don't have a subject set in the Samsung default mail app it will refuse to send. As soon as I add a subject, it'll go without hassle. The log files show: Code: 10/07/2014 13:56:33 [ 4804] [WARN] [firstname.lastname@example.org] /usr/share/z-push/backend/imap/imap.php:470 imap_mail(): No subject field in mail command (2) I am assuming there needs to be a method of writing a [subject] header in the event there isn't one. Additionally, is there a process that will take Out Of Office from the Android Mail app and store it in ISPConfig? I know Roundcube does it, but it would be nice..... Edit: Additionally, I have noticed that the issue relating to 'Subject' appears to affect Blackberry OS 10 also (Not that there is any surprise there).
