Re: Pread error over smb3

[Aki Tuomi via dovecot]

I wonder if you are relying on secondary groups? 
 
If you are, using 
 
service imap {
  extra_groups = somegroup
}
 
can help.
 
Also you could try 
 
service imap {
  executable = /usr/bin/strace -o /tmp/imap -f -ff /usr/lib/dovecot/imap
}
 
might be useful

               not sure what OS you're using, so just a guess:
               but maybe this is
               selinux related or something similar. When it's
               the OS providing
               the
               error code to dovecot, it's very unlikely to be
               anything in dovecot
               itself.
