Hello!We have noticed this problem lately, that when client emails a reply to their ticket, it does not send the "new message" email alert to the agent. The message is added to the ticket, so mail retrieval works. But if the message is added from the web interface, the alert email is sent to the agent. The alert is sent correctly on new emailed tickets, just not on new message to the existing ticket. I have tried normal cron, which we have used as default, rcron and disabling cron and having emails read by the "auto-cron" feature and all of them work the same. Emails are fetched from IMAP mailbox on another server, but since the replies are added correctly and new tickets are read, I believe this is not the issue. Mails are sent with PHP mail and there are no hanging mails in the mailer queue or notice in the mailer logs so it seems those messages are not sent at all.osTicket v1.10 (901e5ea)OS: Debian GNU/Linux 8.7 (jessie)HTTP server: nginx/1.10.2Mailer: Postfix 2.11.3MySQL: 10.1.21PHP: 5.6.30-0+deb8u1
