There are a couple of things to note here:
- If Create Account is not enabled under MailCheck settings, the from address must match a trudesk user email address. If it is enabled, an account will get created for the user with the from address as the username.
- If for any reason the parser fails to parse the body of the email, it will mark the email as read and drop processing it. (I do not see this as the case if the first interval is processing the mail)
There were some event leaks prior to v1.0.5, some of these changes may cause the issues you’re experiencing. I will try to reproduce tonight and push a fix if need be.
