Re: Mailbox on NAS

This is a know 'move' issue with mounts to/from logical high level
networking file systems

The reason why this works for ramdisk mounts is because the ramdisk is a
local low io dev to the system

You could try to mount from an iSCSI drive (if your nas/san support it) as
the target is considered as a local harddisk ressource even if finally
hosted on a different system
And Iscsi is very 'performent' compared to 'high level' network file systems
like nfs, ...

  Objet : Re: [xmail] Mailbox on NAS


  As my understanding for folder domains will use when send to local Email
only, it mean for outside Email,
  no need to care about domains folder. It correct?

  for testing update
  I try to debug XMail logs and found error when move file from

  /var/MailRoot/tmp/<files name>
/var/MailRoot/domains/<domain>/<user>/Maildir/new/<files name>

  after more check /var/MailRoot/tmp/<files name> never receive local Email
<Outside mail it Ok>, It mean from spool folder cannot move to tmp folder it
correct?

  Please help me to explain XMail flow for sending Email.


  PS: I very sure on permission on NAS, because if I move all MailRoot to
NAS everything work.

    And while your right a slight decrease in speed due to having to copy a
file. It would will be dwarfed by the speed of both the lan and nfs in
he's/her's case. As it going to a nas device which in and of it self is
going to be a bottleneck (poor back plans, nics, os, caching systems,
etc)...

    Ps. Also for anyone running dovecot moving your indexes to a ramdrive,
also does wonders. And having it rebuilt the indexing on a reboot for us is
a plus.
