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 [email protected] goes to /home/vmail/domain.com/user/Maildir which contains the real mail BUT login id [email protected] will create new directory /home/vmail/Domain.Com/user/Maildir Please guide me where to look at to resolve this. Thank you. Mani
