Mail (postfix/courier) was working fine on my server till yesterday night. All of sudden I get this error in mail.info: Jun 30 14:13:08 chades pop3d: chdir /var/vmail//var/vmail/site1.com/info: No such file or directory Jun 30 14:13:09 chades pop3d: chdir /var/vmail//var/vmail/site2.com/info: No such file or directory It tries to chdir to var/vmail//var/vmail/... I searched everywhere to find out why it puts the mailbox base infront of the mailbox path making an non-existing path but I could not find anything. Cause of this path the mail delivery does not work. Relative settings on my postfix's main.cf: virtual_alias_domains = virtual_alias_maps = proxy:mysql:/etc/postfix/mysql-virtual_forwardings.cf, mysql:/etc/postfix/mysql-virtual_email2email.cf virtual_gid_maps = static:303 virtual_mailbox_base = /var/vmail virtual_mailbox_domains = proxy:mysql:/etc/postfix/mysql-virtual_domains.cf virtual_mailbox_limit_maps = proxy:mysql:/etc/postfix/mysql-virtual_mailbox_limit_maps.cf virtual_mailbox_limit_override = yes virtual_mailbox_maps = proxy:mysql:/etc/postfix/mysql-virtual_mailboxes.cf virtual_maildir_extended = yes virtual_maildir_limit_message = "The user you are trying to reach is over quota." virtual_minimum_uid = 303 virtual_overquota_bounce = yes virtual_transport = maildrop virtual_uid_maps = static:303 I searched the ISPConfig database, the postfix configuration, the mailbox permissions. I found nothing. Note that the server was working fine till yesterday and I did nt changed anything to it! How this problem appeared and how to solve it? Any ideas? Thanks in advanced.
