Sys_Email records switching between state "send-ready" and "some sys_id" and notifications delayedIssue Symptoms: When using your own SMTP server different than the OOB SMTP Server provided from ServiceNow, messages are not sent out for a period of time (this could be from few minutes to many hours). Checking the sys_email table, records seems regularly switching between type "send-ready" and an unknown sys_id not related to any sys_email records. The messages are eventually delivered and then the state changes to "Sent" as expected but the message arrives later than expected by the customer.CauseWhen an email is to be processed, it first goes to the SMTP sender job queue and then once processed it goes to the sent or send-ignored or received etc queue. In this case, you can see the sys_id of the 2 SMTP jobs that you have because there is either a huge email queue to process or an SMTP Server delay. The 2 sys_ids are the sys_ids of the SMTP jobs. So the fact that we see the sys_id means that the message is not sent yet. ResolutionContact your email administrator as this delay is usually due to lack of availability of the external (non-ServiceNow) SMTP Server. Check the creation date and update date of the sys_Email records of the period of time of the issue. If the time difference between creation and last update of the sys_email record is taking longer than usual (For example, 20 minutes or even hours), it means it is likely that you have an issue in your SMTP Server (timeout or unresponsive).
