Invalid/Unmapped Key with Last Login Plugin
OS: Ubuntu 22.04.1 Dovecot: 2.3.16 (7e2e900c1a)
Hello all! I have the last login plugin working with the IMAP service however with LMTP, it errors. I do not necessarily need / want the LMTP service and did not explicitly enable it but it is throwing an error in my logs.
Jul 17 10:22:14 lmtp(184051):Error: last_login_dict: Failed to write value: dict-server returned failure: sql dict set: Invalid/unmapped key:shared/last-login/lmtp/username@domain.com/ (reply took 0.234 secs (0.001 in dict wait, 0.033 in other ioloops, 0.030 in locks, as
ync-id reply 0.000 secs ago, started on dict-server 0.220 secs ago, took 0.000 secs))
It would be nice to get rid of this error one or another: either disable last login for LMTP or get it working.

Hi Adam
maybe you do have last_login enabled for lmtp without realizing it. What is your actual setting for mail_plugins in the protocol lmtp section?
If it something like:
mail_plugins = $mail_plugins sieve
then you are adding the following definition too from the general definition
mail_plugins = " quota mailbox_alias last_login"
So it would make sense to remove last_login from the general mail_plugins setting and add it only to the protocol specific mail_plugins section for the protocols where you want it be used.

Hi Adam
My recommendation, before disabling lmtp, would be to investigate and maybe revise this point "I do not necessarily need / want the LMTP service and did not explicitly enable it". That error is being generated by a login to lmtp. So what is logging in despite you not needing lmtp?
If for example you are using lmtp to deliver email from postfix to dovecot, disabling lmtp will stop the flow of new email.
John
Yikes, this is my bad! I AM using the LMTP service for delivery. What I meant was that I do not necessarily need to track the logins to the LMTP service. I suppose it wouldn’t hurt to track them though. Any idea why it would be throwing this error? Which key is it expecting to be mapped? Am I missing a configuration specifically for this? Should the last login for LMTP use the same dict as the IMAP configuration?
Here’s my IMAP configuration:
protocol imap {
mail_plugins = $mail_plugins imap_sieve imap_quota last_login
}
Here’s my LMTP configuration:
protocol lmtp {
mail_plugins = $mail_plugins sieve
}
And then here’s my main mail_plugins configuration:
mail_plugins = $mail_plugins quota mailbox_alias last_login
Finally, here’s my dict for the last_login:
plugin {
last_login_dict = proxy::sql
last_login_key = last-login/%{service}/%{user}/%{remote_ip}
last_login_precision = ms
}
dict {
sql = mysql:/etc/dovecot/inc.d/inc.lastlogin.sql.conf
}
All the documentation I have seen everywhere shows that to enable a plugin, you must add it to the main mail_plugins as well as in each protocol you want the plugin enabled but it appears that the $mail_plugins is a variable and adding them there anyways. Is this correct? If so, why does most of the documentation I am reading on a daily basis show to add plugins to the main mail_plugins as well as the protocol?
Any further help is definitely appreciated so I can get this figured out.
Thank you!

Hi Adam
not sure if you saw it but in my earlier response I gave the info about excluding last_login plugin for services where it is not needed. You have it configured globally at the moment.
John
Yes, I did see that, thank you. If I did want to get this working globally, do you know what the issue is here and how to resolve it? I think it has something to do with my database table but I am not positive what the issue is. Here’s my database table (MySQL):
CREATE TABLE mailboxLastLogin (
email varchar(192) NOT NULL DEFAULT ‘’,
service varchar(16) NOT NULL DEFAULT ‘’,
timestamp bigint(20) NOT NULL,
ipaddress varchar(40) NOT NULL,
createdAt datetime NOT NULL DEFAULT current_timestamp(),
PRIMARY KEY (email)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_general_ci;
I also have two triggers on this table so when a new row is inserted or
an existing row is updated, a new row is inserted into another tables
named mailboxHistory. This is working fine and should not be causing
any issues with LMTP trying to query itself.
BEGIN DECLARE mailboxUuid VARCHAR(36);
SELECT uuid INTO mailboxUuid FROM mailbox WHERE email = NEW.email;
INSERT INTO mailboxHistory (`mailboxUuid`, `service`, `command`, ipaddress, uuid)
VALUES (mailboxUuid, NEW.service, 'login', NEW.ipaddress, uuidv4());
END
BEGIN DECLARE mailboxUuid VARCHAR(36);
SELECT uuid INTO mailboxUuid FROM mailbox WHERE email = NEW.email;
INSERT INTO mailboxHistory (`mailboxUuid`, `service`, `command`, ipaddress, uuid)
VALUES (mailboxUuid, NEW.service, 'login', NEW.ipaddress, uuidv4());
END
CREATE TABLE mailboxHistory (
id int(11) unsigned NOT NULL AUTO_INCREMENT,
uuid varchar(36) DEFAULT ‘’,
mailboxUuid varchar(36) NOT NULL DEFAULT ‘’,
service varchar(16) NOT NULL,
command varchar(36) DEFAULT NULL,
extra longtext DEFAULT NULL,
ipaddress varchar(40) NOT NULL,
createdAt datetime NOT NULL DEFAULT current_timestamp(),
PRIMARY KEY (id),
UNIQUE KEY UUID (uuid)
) ENGINE=InnoDB AUTO_INCREMENT=2047 DEFAULT CHARSET=utf8mb4
COLLATE=utf8mb4_general_ci;

Hi Adam
the solution is to change
mail_plugins = " quota mailbox_alias last_login"
to
mail_plugins = quota mailbox_alias
(without the last_login)
The last_login should be configured inside the protocols where you need it, like imap. I don't think it's useful to have the plugin setup for services different to imap, pop3 and smtp where you have users logging in. If you want to have last_login for lmtp without that error, I'd need a bit more info
What are the contents of /etc/dovecot/inc.d/inc.lastlogin.sql.conf (masking any passwords) and what is the output of doveconf plugin/last_login_key
