But I discovered a malfunction. If one user tries to login using his username in mixed upper and lowercase the script throws an "User not found" error. Say he enters Foo@bar.org, but in the database the mail address is saved as foo@bar.org, he cannot login. Outlook, Thunderbird and Squirrelmail don't convert the username to lowercase. Roundcube does.

To fix this issue, the username should be converted into lowercase before the database lookup takes place. Simply add the following after line 46 and it works:

Code:

$username =~ tr/A-Z/a-z/;

If you do that you should change:

mail_location = maildir:/var/mail/virtual/%d/%n
to
mail_location = maildir:/var/mail/virtual/%Ld/%Ln

(this should be changed anyway ;-))
