The aox retain mail command inserts or updates a mail retention policy. Users will not be able to delete mail if it matches the policy.
Each policy has a duration, and optionally a mailbox to which it applies and/or a search specification.
If it applies to a mailbox, it also applies to all children of that mailbox. If you specify a search, then the policy applies only to messages that match that search, otherwise it applies to all messages.
The simplest policy is one that matches all messages:
aox retain mail 7
A little more complex is one that matches all messages in certain mailboxes, such as this, which preserves mail forever in the mailboxes /archive/this, /archive/that, etc.
aox retain mail forever /archive
It is also possible to specify a search. This preserves all mail from/to/… exemplo.com.br for 14 days:
aox retain mail 14 address exemplo.com.br
The last example has both a mailbox and a search:
aox retain mail 90 /archive/sales address exemplo.com.br
