update 7.5.1 mailbox quota to 0 kb

[xerrera]

Hello,

Is there anything known of the following issue: after upgrading my plesk box to 7.5.1. all mailboxes were set to 0kb.

Most of them were working normally, but some generated error return messages that the mailbox was full.

I was curious if this is a known issue, and how to prevent/solve it instead of turning all individual mailboxes to unlimited.

Thanks
Regards
Joost
