Sender Service and Selector There are many Service and Selector pairs for a sender. You can use these 2 fields to determine which service the message was from and why the message was generated.

Destination Service and Selector There are many Service and Selector pairs for destination. You can use these 2 fields to determine to which service the message was sent. Service Selector gmail-ui sent-on-behalf-of-user Message was sent to Gmail UI and is kept as a copy in the user's Gmail Sent label. gmail-ui null Message was sent to Gmail UI. mailing-list-server spam-check Message was sent to Google Groups and was spam-checked. mailing-list-server null Message was sent to Google Groups. mailing-list-server moderation Message was sent to Google Groups and is pending administrator moderation. mailing-list-server archive Message was sent to Google Groups and is archived. gmail-for-work-catchall smtp-outbound gmail-delivery-server Message had unrecognized recipients and was delivered according to a catchall rule. Message was sent to outbound SMTP server and handled by Gmail delivery servers. Gmail logs in BigQuery 7

smtp-outbound smtp-outbound smtp-outbound smtp-outbound google-apps-for-work google-apps-for-work-starter gmail-notification relay Message was sent to outbound SMTP server and handled by G Suite basic. Message was sent to outbound SMTP server and handled by G Suite basic. Message was sent to outbound SMTP server and handled by Gmail notification. Message was sent to outbound SMTP server and handled by Gmail relay servers. smtp-outbound gmail Message was sent to outbound SMTP server smtp-outbound gmail-for-work Message was sent to outbound SMTP server and added by Gmail for business policies. smtp-outbound null Message was sent to outbound SMTP server. Action types You can use this field to determine which stage in the email delivery pipeline the message went through. of relevant action types is detailed below: 1 Message received and handled by inbound SMTP server. 2 Message inserted to Gmail delivery server and prepared for delivery. This is usually the next step following 1, or the first step if you send from the Gmail UI. For incoming messages, policies with reject dispositions are usually evaluated here; for example, an attachment compliance policy that rejects incoming messages with archives. 3 After 2 (message inserted into Gmail delivery server), this means the message was handled by the Gmail delivery server and delivered to another server; for example, the outbound SMTP server. Policies with dispositions other than reject are evaluated here; for example, the attachment compliance policy that strips an attachment if it s an archive file. 10 Message handled and sent out by outbound SMTP server. 14 This means a temporary error occured when Gmail delivery server tried to deliver the message, and the message has been scheduled for retry. This is usually caused by external or internal servers that Gmail delivery server talks to being temporarily unavailable; retry later. For example, we tried to deliver the message to an external SMTP server, but got a temporary error (4xx) back. 18 Message bounced by Gmail delivery server. When we can t deliver the message, we bounce the message. Sometimes you can find out what happened by reading message_info.description. Some common reasons are: Gmail logs in BigQuery 8

The recipient server didn t accept our requests. We ve retried many times due to temporary errors, but still failed to deliver the message. We can t evaluate policies in insert time (message_info.action_type == 2), deferred the evaluation until delivery time, and found out the message triggered a reject disposition. The recipient is unrecognized and there s no policy triggered to change the primary delivery route. 19 Message dropped by the Gmail delivery server. This can occur: If a message being sent triggers admin quarantine consequences, the original message is dropped and a copy of the message is added in the admin Quarantine Manager. For exchange journaling message, we deliver the wrapped inner message, and dropped the original message. For inbound messages, Gmail can block and drop messages; for example, if: Not RFC 5322-compliant Sender violates bulk senders guidelines For this type of drop, you should be able to see the detail reason through message_info.description for that message where message_info.action_type = 1. There s policy triggered to remove the primary delivery route and add other routes. We dropped the original message and delivered copies to other routes. The recipient is an unrecognized address and there s policy triggered to add delivery routes for the message. We dropped the original message and deliver copies to other routes. 55 Message was re-inserted into Gmail delivery server, caused by policies that modify the primary delivery route or envelope recipient. 48 Message received and handled by inbound SMTP server in relay mode. 49 Message sent via outbound SMTP server in relay mode. 69 This action indicates manual spam correction (eg: report as phishing, report as spam/not-spam etc.) Gmail logs in BigQuery 9

Message set types You can use this field to see attributes of the message; for example, being sent or received. 9 Message being received; for example, an incoming message. 8 Message being sent; for example, an outgoing message. 11 Message had sender or recipients outside your domain. Or, for message being received, if message set 27 is missing, this means we couldn't authenticate the sender; will treat the message as having a sender outside your domain. 10 Message internal to your domain. 12 Message had some recipients internal to your domain and some recipients outside your domain. This message set may appear only when: There are multiple recipients. A message is being sent (for message being received, we enforce that the recipients all belong to the same domain). Action type for the message is 2 (we split multirecipient messages to single-recipient messages after that). Messages with this message set would have policies affecting both internal and external triggered. 1 Incoming message from outside your domain. This message set doesn t appear at the same time as message set 10. 2 Outgoing message sent to other domains. This message set doesn t appear at the same time as message set 10. 27 Sender has successfully passed SPF/DKIM/DMARC authentication. If the sender isn t authenticated, then we don't trust the sender domain; the message won t be considered internal. 7 Message was classified as spam by Gmail spam filter. 47 Message was detected to be spam by tag-and-deliver information in your inbound gateway settings.
