dovecot quota-warning detection mail

[森川 孝司]

Hi,Kouga-san

When quota-warning works normally
I'm sending an email to "From: <Postmaster at example.co.jp> to =
<abc-xyz-unyo at example.co.jp>"

When it doesn't work
An email was sent to "From: <Postmaster at example.co.jp> to =
<abc-xyz-unyo-sekkei>"
"Recipient address rejected: User unknown in local recipient table"

It will be.

cat /etc/dovecot/conf.d/90-quota.conf
-------------------------------------------------- ------------
plugin {
   quota_warning = storage = 95 %% quota-warning 95% u
   quota_warning1 = storage = 90 %% quota-warning 90% u
   quota_warning2 = storage = 85 %% quota-warning 85% u
   quota_warning3 = storage = 80 %% quota-warning 80% u
}

service quota-warning {
   executable = script /usr/local/bin/quota-warning.pl
   user = dovecot
   unix_listener quota-warning {
     user = vmail
   }
}
-------------------------------------------------- -------------

And it is set.

Thank you.

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.

Kouga

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.
