Problem creating directory

[mytux]

We are using our NAS with open-E Data storage Server on it to store the mail of our ADSL customers.

2 pop servers are connected to it. They are running on linux, and the NAS is mounter via samba (cifs, not smb) with this line in /etc/fstab/

//192.168.0.10/mail/ /home/surgemail cifs user=xxx,password=xxx,setuids,uid=mail,gid=mail 0 0

When we create a user on our pop servers, the directory of this user is not created and is only created when the user receives a mail (it's normal and should work like that).

But since we migrated the NAS, it doesn't work anymore.

When we send a mail to a newly created mailbox, we receive this message :

554 Failure Permission denied

When debugging, we see that the directory of the new email address is not created.

After sending 2,3 or 4 mails, the directory gets created. The number of mail we have to send for the directory to be created is not constant... We came then to the conclusion that the NAS was perhaps overloaded or something like this, and couldn't do the creation of the directory.

Could you help us with that ?

We would like to tweak the settings on samba on the NAS, but we don't have access to all the config... :-)

Sorry to say we do not provide shell or some root access. We may need to look into logs to see if there are any errors or we may somehow need to create an update. It will take some time to create an update.

I can provide you all the logs you want.
I already looked at the logs on the NAS, I do not see anything concluant about that.
On the Linux boxes I have stuff like that in the logs (dmesg) :

I don’t have any knowledge of this type of setup with your email config. If you are able to create directories and access without the email system on its own but not when using our system there maybe something else that is required to open on our end or some type of access. If you can find this out and send full logs to support@open-e.com we could look at it.
