We are migrating from an old Centos 5.5 system to a new Centos 6.4 server. The postfix version looks the same, but Dovecot has gone up from 1.x to 2.x. It uses MySQL to store the mail account details and its managed with pfadmin.
I have used rsync to copy the
/var/vmail folder from old to new server. I have got postfix and dovecot installed, pfadmin is working, as is mysql. But I am having major problems with the permissions for the
drwxrwx---. 34 vmail vmail 4096 May 28 10:03 vmail
postfix:x:89:89::/var/spool/postfix:/sbin/nologin dovecot:x:97:97:Dovecot IMAP server:/usr/libexec/dovecot:/sbin/nologin dovenull:x:498:499:Dovecot's unauthorized user:/usr/libexec/dovecot:/sbin/nologin mysql:x:27:27:MySQL Server:/var/lib/mysql:/bin/bash vmail:x:125:12::/var/vmail:/usr/sbin/nologin
relevant lines in dovecot.conf
first_valid_uid = 125 last_valid_uid = 150 mail_location = maildir:/var/vmail/%d/%u mail_privileged_group = mail mbox_write_locks = fcntl
When I telnet onto port 25 and 110 (for PF and Dovecot testing). The smtp session goes ok and the pop3 session crashed out.
maillog has the clues - Here is what Postfix is generating:
warning: maildir access problem for UID/GID=150/12: create maildir file /firstname.lastname@example.org/tmp/1369997999.P1913.IS-20698: Permission denied
and for Dovecot:
dovecot: pop3(email@example.com): Error: file_dotlock_create (/firstname.lastname@example.org/dovecot-uidlist) failed: Permission denied (euid=125(vmail) egid=125(vmail) missing +w perm: /email@example.com, euid is not dir owner)
- So basically neither process can write to the mail directories.
How do I get all my permissions in-line?
