Squirrel Mail Login ID creates new domain folder

[mani_jeee@yahoo.com]

Hi,

I am running postfix with dovecot POP3/IMAP and MYSQL with SquirrelMail (http://www.linuxmail.info/)

my Maildirs are in /home/vmail/domain.com/user/

When i log into squirrel mail using capital letters in login ID, it creates a new domain folder in vmail directory. i.e.

login id user@domain.com goes to /home/vmail/domain.com/user/Maildir which contains the real mail
BUT
login id user@Domain.Com will create new directory /home/vmail/Domain.Com/user/Maildir

Please guide me where to look at to resolve this.

Thank you.
