dovecot quota-warning detection mail

[Koga Hayashi]

Morikawa,

What do you mean by "logged-in user"?

%u stands for the username.
If, for an example, user "morikawa" exists in your dovecot server (I mean as local user), your quota warning configuration should be fine.
But if user "morikawa" does not exist in your server, and, dovecot can't resolve the username to the mail address, then the quota warning mail be rejected because dovecot can't find the "username" in local recipient table.

A little more information about your server environment will be appreciated.

Hi, all.
we use quota-warning emails to notify you of quotas.

In rare cases, the email address has changed to the logged-in user.
(Because the address of %u is passed as the logged-in user.)

So I couldn’t send the email with “Recipient address rejected: User unknown in local recipient table”.

Why does my email address change to a logged-in user?
%u of "quota_warning = storage = 95 %% quota-warning 95% u"
The output is the logged-in user.
