Original GitHub issue: https://github.com/modoboa/modoboa/issues/1240

Originally assigned to: @tonioo on GitHub.

I'm impressed by the great functionality and how easy modoboa is. Thank you very much! :)
However poking around a litte I guess I found a bug:

Impacted versions

Modoboa: 1.9.0.
installer used: Yes
Webserver: Nginx

Steps to reproduce

Login as superadmin and go to Identities
Create a new superadmin accout with user name "foo" and some password
Click on "Next" and then enter foo@mydomain.de as E-mail Address. Submit.
Logout
Login as foo
Click on Webmail

Current behavior

Webmail tries to login as user=<foo>:

Sep 20 20:29:27 vs****** dovecot[449]: imap-login: Disconnected (auth failed, 1 attempts in 2 secs): user=, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured, session=<LXLt1KRZvAB/AAAB>

Browser displays:

Error: ['[AUTHENTICATIONFAILED] Authentication failed.']

Expected behavior

Browser displays mailbox. :)

Note

If you change the username from foo to foo@mydomain.de, everything works as expected.
I guess, instead of the username, the webmail should pass the E-mail Adress associated with the username to Dovecot...

I guess the simplest way to fix this issue would be to enforce same values for username and email address once the email address is defined. What do you think?

Good idea, that should do the trick. :)
The error message displayed to the user should explain it a little, e.g.:

"If you define or change the mail address for this account, you need to
change it's username to the same value."

Just a hint would be nice. I was running into same issue after fresh modoboa install. luckily i found this thread. I really think it's a reason to change to other software if webmail (which you run to test after first time installs) is not working! 👍
