I have just installed a mail server following this how-to: http://www.howtoforge.com/virtual_users_and_domains_with_postfix_debian_etch Great how-to. Everything works, but I noticed that when I create a user with quota 4GB and send him an e-mail, everything is ok except the quota. For some reason it was truked to 2GB (2147483647). In mysql database everything is ok. But the value in maildirsize in /home/vmail/domain.tld/user1/ is 2147483647S. I checked every step on how-to and there is no errors. Can you help me with this one? Thanks in advance.
