Search log by email address<\/h2>\n\n\n\n
You can search for specific addresses with the exigrep. Replace email@address with the email address of interest.<\/p>\n\n\n\n

Message Direction<\/h2>\n\n\n\n
Looking at entries in the main log, some of the messages will have an indicator from the following table that tell us the status of the message and\/or where it came from or went.<\/p>\n\n\n\n| <=<\/td> | Indicates the arrival of a message to Exim for handling<\/td><\/tr> |
| =><\/td> | Shows a normal message delivery<\/td><\/tr> |
| -><\/td> | Additional address for the same delivery, i.e. an Email forwarder.<\/td><\/tr> |
| >><\/td> | cutthrough is a router precondition
This option requests delivery be attempted while the item is being received. It is usable in the RCPT ACL and valid only for single-recipient mails forwarded from one SMTP connection to another. If a recipient-verify callout connection is requested in the same ACL it is held open and used for the data, otherwise one is made after the ACL completes.<\/td><\/tr> |
| *><\/td> | delivery suppressed by -N<\/td><\/tr> |
| **<\/td> | delivery failed; address bounced<\/td><\/tr> |
| ==<\/td> | delivery deferred; temporary problem<\/td><\/tr> |
| <><\/td> | For “<>” from the exim manual; Additionally, you will often find A bounce message is shown with the sender address \u201c<>\u201d, and if it is locally generated, this is followed by an item of the form
