Dovecot 2.4 and E-Mail Address as Login Setting
All,
I am running Dovecot 2.4 on a single server, and I am wondering where I can set it to use the full email address as the login name.
I am running Ubuntu 26.04 and its fully updated. I own the server, and the domain. Let me know what information you need to assist me.
Very Respectfully, Daniel Reinhardt

It depends where you keep your users. I am using on one server sqlite for the usernames and on another mariadb and the username query is in the “<path>/dovecot/conf.d/auth-sql.conf.ext“ and the users are created using postfixadmin.

I am using the /etc/passwd file for usernames so its not a fancy setup using anything like SQL.

I have that set to default, and it doesn't allow email address to be used.

Hi Daniel,
I had issues too with using a password file, before I used sql database for the user authentication I used pam authentication which authenticates to the system password file, in Ubuntu it should already have the correct dovecot authentication file in /etc/pam.d

I have that set to default, and it doesn't allow email address to be used.
I get the same error as No Authentication Error.

Have you tried setting log_debug=category=auth and check logs? It might tell you where the problem lies.

Horst,
I have that set to default, and it doesn't allow email address to be used.
I get the same error as No Authentication Error.

All,
I got working with the following edits to auth-system.conf.ext:
userdb passwd-file { driver = passwd-file auth_username_format=%{user|username} passwd_file_path = /etc/passwd fields { user = %{user|username} name = %{user|lower} home = /var/vmail/%{user} } skip = found
And edits to 10-auth.conf
auth_username_format=%{user|username}
I can now authenticate via email address.
I thought I would provide the fix incase others have this issue.

Why would you use an email address for login? Using an username gives you already some sort of 2fa. Only the huge companies that want to track people and have issues scaling, would resort to using email addresses...

From IOS 18 on there are difficulties with the native Apple Mail client connecting using IMAP. After googling I found on the Apple mailing list that it works using Exchange Active Sync (EAS) to connect, but the username had to be an email address not username only. This is the reason why I use the email address for authentication.

Hi Daniel,
This is my personal DokuWiki, maybe you can/would compare your settings to mine:
https://dokuwiki.tachtler.net/doku.php?id=tachtler:dovecot_archlinux#konfigu...
(It's only in German language)
Later in my DokuWiki, I have a SQL configuration with postfixadmin too...
Greetings, Klaus.

Daniel,
I run it thru the converter and it came back as follow
auth_username_format = %{user | lower}

Horst,
I am using the /etc/passwd file for usernames so its not a fancy setup using anything like SQL.

It depends where you keep your users. I am using on one server sqlite for the usernames and on another mariadb and the username query is in the “<path>/dovecot/conf.d/auth-sql.conf.ext“ and the users are created using postfixadmin.
