<font size="+1"><font face="Tahoma">Having upgraded a server, many mail
issues that have beaten me! I have 8 mailboxes running under
Centos, all with simple user names such as john, jr, office, junk etc.<br>
Each is owned by a user of the same name and own password. I made a
mistake and copied a back up when server moved and somehow corrupted
correct permissions. I only use smtp (sendmail) and pop3 NOT IMAP.
Each user has same group name as user. They have no home directory.<br>
<br>
(I have suspicion this is to do with group/wheel but have no idea what
to do!)<br>
<br>
I have the directory structure:-<br>
<br>
/var/mail/mailox name owner=user<br>
/var/mail/new (Empty folder) owner= john 700<br>
/var/mail/tmp (Empty folder) owner= john (sometimes has mail that goes
nowhere - more later) 700<br>
/var/mail/cur (Empty Folder) owner= john 700<br>
/var/.imap 777 <br>
/var/.imap/dovecot-uidvalidity owner=junk 666 The owner seems to
change!<br>
/var/.imap/INBOX owner = junk 777<br>
/var/.imap/INBOX/dovecot.index.log owner=jr 660 The owner seems to
change<br>
/var/.imap/INBOX/dovecot.index.cache owner=jr the owner seems to
change<br>
<br>
Mail would not be delivered to user=john<br>
<br>
deleted user and recreated, which seems to have worked - mail now
delivered<br>
<br>
<br>
However, maillog has weird errors - sample:-<br>
<br>
May 4 23:11:49 server dovecot: pop3-login: Login: user=<junk>,
method=PLAIN, rip=82.69.134.94, lip=185.41.9.25, mpid=21213,
session=<hMBaXYjBvrBSRYZe><br>
May 4 23:11:49 server dovecot: pop3(junk): Error:
open(/var/mail/.imap/INBOX/dovecot.index.log) failed: Permission denied
(euid=1051(junk) egid=1051(junk) missing +r perm:
/var/mail/.imap/INBOX/dovecot.index.log, we're not in group 500(jr))<br>
May 4 23:11:49 server dovecot: pop3(junk): Disconnected: Logged out
top=0/0, retr=0/0, del=0/0, size=0<br>
May 4 23:11:50 server dovecot: pop3-login: Login: user=<jr>,
method=PLAIN, rip=82.69.134.94, lip=185.41.9.25, mpid=21215, TLS,
session=<xuRhXYjBv7BSRYZe><br>
May 4 23:11:50 server dovecot: pop3(jr): Disconnected: Logged out
top=0/0, retr=0/0, del=0/0, size=0<br>
<br>
However, the user/group of these files keeps changing "on its own" - so
dovecot is doing the changes.<br>
<br>
*** Note even with these errors it now seems to work the mailboxes, but
any help very, very gratefully received!<br>
