TITLE:

Migration from DirectAdmin has a problem with empty mailboxes​

PRODUCT, VERSION, OPERATING SYSTEM, ARCHITECTURE:

Plesk Onyx 17.5.3 #1
Plesk Migrator 2.6.3-0
Ubuntu 14.04.5 LTS‬​

PROBLEM DESCRIPTION:

When migrating e-mail box from a DirectAdmin server that has just been created (no mail received yet), the migrator gives the following error when syncing:

Failed to copy mail messages of mailbox '[email protected]': Command execution failed on the local server with non-zero exit code.
command: /usr/local/psa/admin/bin/mailmng-core --set-mailbox-disk-quota --domain-name=domain.com --mailname=emptymailbox --disk-quota=-1
exit code: 1
stdout: Maximal allowed number of attempts to create a maildirsize file exceeded
System error 11: Resource temporarily unavailable
Fatal error: plesk::mail::FSError(unable to store mbox quota: Success: "/var/qmail/mailnames/domain.com/emptymailbox")

stderr: DEBUG MaildirPPManager::setMailboxQuota(..., -1)
Maximal allowed number of attempts to create a maildirsize file exceeded
System error 11: Resource temporarily unavailable
Fatal error: plesk::mail::FSError(unable to store mbox quota: Success: "/var/qmail/mailnames/domain.com/emptymailbox")​

STEPS TO REPRODUCE:

Create a new mailbox on DirectAdmin (make sure it hasn't received any mail yet) and try to migrate the account to a plesk server.​

ACTUAL RESULT:

Mail box doesn't get created and migration fails.​

EXPECTED RESULT:

The mailbox should have been created.​

Hello Fu-Raz,

Could you please check the following kb: Could not create mail account: "Maximal allowed number of attempts to create a maildirsize file exceeded"
Let us know the results.

Hi Peon,

I've checked the kb, but shouldn't this error come up all the time if that's the case? It only happens on a migration where there's an empty mailbox. If I delete the empty mailbox, the migration completes without any problems.

Could you clarify, does the affected Plesk server contains "/" symbol in hostname?

I tried to set hostname with "/" symbol in Ubuntu server 14 and in Centos 7, but system refuse creating such hostname.
