This week I upgraded postfix from a RHEL 3 box to a new install with
CentOS 6.2 and Postfix 2.6.6 and Dovecot 2.0.9
Most things are working (logging in, sending mail, etc).
But I'm having some issues receiving mail. But not all accounts are
having this trouble.
My setup is that I have /home mounted NFS4 to my postfix server's /home.
And I have /var/spool/mail mounted NFS4 to /var/spool/mail.
/var/spool/postfix would be a local mount.
What seems odd is that I've been getting some files like
1370016781.P17278.hostname
under /home/user/mail/tmp and /home/user/mail/new
I don't think these directories were there previously.
And in some instances mail is bounced back when sending to a user:
[email protected]
#< #5.2.0 X-Postfix; maildir delivery failed: create maildir
file /home/guenther/mail/tmp/1369982045.P9259.hostname:
Permission denied> #SMTP#
I tried temporarily setting permission to 777 under mail/tmp but that
didn't help so I set it back to 755
I suspect I'm just missing something when converting from the earlier
postfix to the newer postfix (and dovecot). Why am I getting these tmp
and new files under /home/user/mail?
Its probably not related, but I noticed with my NFS4 mount that I can't
use dot locking. I had to use fcntl instead.
