Mail Queue
Allows you to manage the queue of mail that for some reason cannot be sent or received right now. The module allows you to manage both incoming and outgoing deferred correspondence. To analyze possible reasons for the delay of correspondence in the queue, you can use information from the corresponding column of the table for each letter. There are both individual and group actions with items in the queue (clearing the queue, resending a single letter, deleting single letters from the queue, and resending all correspondence from the queue).
Checking Mail Server Settings
It is recommended to check the correctness of all DNS and mail server settings using the service mail-tester.com.
With the correct configuration, the mail server on SafeUTM should receive 10 points out of 10.
