Missing inbox emails after restore

Hi guys,
I did a backup with CWP backup system and restored using the same system. I only had a choice to restore all, but that's ok. The account was about 4.6gb and was only used for email and had about 10 accounts.
Once I restored the account the emails in the inbox of the clients started to disappear, in fact a whole months worth in each email account. The backup and restore was completed within 15 minutes of taking it and I don't think it has missed out anything.
The clients are using Imap to access the server.
I tried to sync the folders and managed only to get the Spam, Deleted and sent items restored... but not the inbox.


Any clues what might be happening?

OK... this is solved.
It was me
AntiSpam/AntiVirus (recommended):

Drop all emails if no rDNS/PTR

Installs DKIM & SPF, enables DKIM for New Accounts and Domains
Install Policyd (recommended):   

Installs Policyd, enables hourly email limit per domain. I needed to go in to the Postfix mail manager and tick the following boxes:

Once the mail server was rebuilt, the inbox mails started to flow back in to the mail clients.

Such a stupid thing not to have done... Sometimes I can't see the wood for the trees

It happens to all of us.

Helps to talk the problem out sometimes.
