I've noticed that support ticket emails from my OSTicket install (v1.9.12) are not received by any Hotmail or Outlook accounts. Gmail receives them just fine. How can I get these other accounts working? Perhaps there's a mime setting or something?
Perhaps you would want to check with outlook.com/hotmail?especially in your spam box there.
The emails are not in the spam folder. I'll look into mime, header, and spf needs for hotmail/outlook. it has something to do with the way the default php mail function is forming the email.
Could you switch to SMTP?
What MTA (local mail server? Gmail?) is your osTicket using to send mail?Microsoft (Outlook/hotmail/Exchangeonline) has a blacklist processor that acts on incoming email prior to the filter that puts messages in the spam folder.It is likely your messages are being killed by that step, and there is nothing on the Hotmail/outlook side that shows that. You would have to check the logs on whatever server osTicket is connecting to to send the messages. If Microsoft is blacklisting you, your MTA logs should have a Status 5.5.0 message saying so.
