OSTicket has been throwing mail-related errors since November 1st. These are visible via "Dashboard" --> "System Logs".
The exact error message is as follows (with our email address redacted, of course):
Mailer Error
Unable to email via SMTP:smtp-relay.gmail.com:587 [helpdesk@REDACTED] Failed to set sender: helpdesk@REDACTED [SMTP: Invalid response code received from server (code: -1, response: )]
As for as I can tell our emails are being delivered, so this is strange. We are using Google Apps fro Business by the way.
Thanks in advance
