When I use Thunderbird to add my email, the username part is only abc (not abc@example.com), I had to manually add the @example.com part.

In the same way, when login using front end web browser, I have to use the full email address.

Is there any way to config SOGo and other backend components to allow login with Thunderbird/Outlook and frontend web browser with only username without domain part?

I had add the parameter SOGoMailDomain = "example.com"; to sogo.conf and auth_default_realm = example.com to dovecot.conf but no luck.

I only use one domain only.

IDFieldName and UIDFieldName is "mail" (w/o quotes)
bindFields = (mail);

bindAsCurrentUser = YES;

and

SOGoForceExternalLoginWithEmail = NO;

I had added

bindFields = (mail,cn);

but only postmaster (w/o domain part) works. Other accounts are still not accessible w/o the domain part.

Thank you and regards,
