 Yes, I forgot to mention that the same thing applies to doveadm too.

Hi Sami,

Thanks, for taking the time to look at this.

For the archives, the resolution is in line below.

Does anyone have an Idea how to fix this?


Perhaps see if there are any denials in SELinux audit log:


Selinux is in permissive.

If I do:
(vmail1 pts9) # ll /proc/self/io -r 1 root root 0 Jul 30 15:27 
/proc/self/io
(vmail1 pts9) #

It is obvious to me why I get permission denied. The problem is you
cannot chmod on /proc. I suspect I have something mis-configured but
the question is what?


service lmtp {
executable = lmtp -L
inet_listener lmtp {
  address = 127.0.0.1
  port = 24
}
process_min_avail = 5
unix_listener /var/spool/postfix/private/dovecot-lmtp {
  group = postfix
  mode = 0600
  user = postfix
}
user = vmail
}

please remove user = vmail from here or change it to root.


Actually the above works OK but you gave me the clue I needed to
find the actual problem. I looked at the log message again and
realized that it says doveadm is having problems.
Something like this:
Jul 22 12:52:04 vmail2 dovecot: doveadm: Error: open(/proc/self/io) failed: 
Permission denied

So I took your advice and found that I had the following in my dsync
config:
service doveadm {
  inet_listener {
port = 2525
  }
  user = vmail
}

Removing the user = vmail above fixed the problem.

Thanks again.
