Hi, Today a mail user called us asking why he didn't receive the mails he was sent. The mail server blocked the reception saying: can't create user output file. Command output: postdrop: warning: uid=10091: Disk quota exceeded sendmail: fatal: user1.domain(10091): Error writing message file procmail: Quota exceeded while writing "/var/www/web30/user/user1.domain/Maildir/tmp/1206565347.15534_0.ns2.lolo.com.ar" I don't understand why this happends because I've checked and the users Maildir and the domain still has enough available space. Thanks to all! PD: this happends ONLY whit this user
