FortiMail 3000F
Firmware version: 7.4.2

Two problems occurred when registering approximately 5,000 new aliases via CLI to FortiMail, which already has 100 aliases registered.

1. When mail is received by newly registered aliases and existing aliases, mail is not delivered to members (user unknown is displayed even though the user is already registered).

2. Adding/deleting a member in the GUI is not reflected in the alias where the above problem occurs (the member is deleted in the GUI, but the member still receives mail via the alias).

The first problem stopped after I forced failover from primary to secondary in HA configuration,
However, problem 2 continues to occur.

Are these known issues?

Is there a limit to the number of aliases that can be registered or the maximum number of members that can be registered in one alias?

Is there any way to recover problem 2 ?

The second problem was resolved after a reboot.

Thank you all for your concern. Thank you very much.

You can still try update to 7.4.3 and see if it fixes the issue.

Thank you for your reply, AEK.

I am not in an environment where I can easily perform updates without reliable information on how to fix it.
I am posting this in this community to get more information since there is no history of this bug fix in the release notes for v7.4.3 and higher versions that you provided.
Do you have any other useful information?
