cannot create new mails on domain

[voodookid]

Hello,

I'm trying to import a large number of mail accounts from CommuniGate server to Plesk 9.2.1 on Debian.
After importing 48123 number of accounts the import stops.
Running the add email command from shell gives me the following error :

hv2m69:~# /opt/psa/bin/mail -c [email protected] -cp-access false -mailbox true -passwd alabala
Fatal error: boost::filesystem::basic_filesystem_error<boost::filesystem::basic_path<std::string, boost::filesystem:ath_traits> >(boost::filesystem::create_directory)
ERROR: PleskUtilException

6: cuMail.php:654
cuMail->cmdCreate(string '[email protected]')
7: cuMail.php:468
cuMail->execute()
8: mail.php:27

Appears to be some kind of file system restriction.
Did anyone received this error or knows how to disable the restriction ?

Thanks in advanced.

Hello again,

Found out what the problem was. I have reached the maxim number of sub-folders that can be created in linux : 32000.
This restriction is set in kernel.

Another weird fact is that I have 32,000 sub-folders in /var/qmail/mailnames/domain.com/ and inside psa db I have 48,123 records related to mail accounts.

I have two options here :
- change the kernel limit related to sub-folders - I don't think this is suck a good idea.
- change the qmail folder structure and make master sub-folders names containing just one letter, and inside each of this sub-folders store each account that starts with the specified letter.

What do you think about this second approach, can this be achieved ? Has anyone tried this before ?

Thanks in advance.
