Mailbox purging carries on continuously in the background. The process pauses/sleeps between each mailbox by a user defined interval (default is 1 minute). What's purged is defined in the ''Class of Service (COS)'' for a particular mailbox - see the '''Email Retention Policy''' on the ''Advanced'' tab in the admin console (it can be overridden for individual mailboxes in the ''Advanced'' tab of the account config). | Mailbox purging carries on continuously in the background.

=== Enable DKIM === | |||
[[Acronyms#DKIM|DKIM]] allows for the signing of certain fields of an email (for example the From: field, allowing the recipient to trust that the email is from whoever it purports to be and not from a spammer). This is achieved by adding a DKIM signature to an email, which can be cross referenced with a public key provided in DNS for the sending domain. | |||
'''DKIM is not available in versions prior to Zimbra v8 !''' | |||
For more info on DKIM see... | |||
* http://www.dkim.org/ | |||
* http://www.wikipedia.org/wiki/DomainKeys_Identified_Mail | |||
For fuller, Zimbra specfifc instructions see... | |||
* http://wiki.zimbra.com/wiki/Configuring_for_DKIM_Signing | |||
To set-up | |||
# Create the DKIM keys on your Zimbra server for your domain | |||
## Log into your Zimbra server as the Zimbra user | |||
## Run DKIM key utility | |||
##* EG <code> /opt/zimbra/libexec/zmdkimkeyutil -a -d domain.com </code> (replace <code> domain.com </code> with your domain) | |||
# Add the public key generated into your DNS as a TXT (text) record (the field names will be vary dependant on your provider's DNS managment interface) | |||
#* EG: Label/Name/Entry: <code>5E56FFDC-11F6-11E2-9862-DA8801AF17E6._domainkey</code> | |||
#* EG: Data/Target: <code>v=DKIM1;=rsa; p=MIGfMA0GCSqGSIb3...<etc - your key will be longer!></code> | |||
# Confirm the DNS entry is correct | |||
#* EG <code> dig -t txt 5E56FFDC-11F6-11E2-9862-DA8801AF17E6._domainkey.domain.com </code> | |||
