Auto archiving

[Danny <danny@xxxxxxxxxxxxxx>]

Hi list,

I have quite a few mailboxes, and many of these are from lists. How can I have
mutt autoarchiving all messages in all mailboxes that are more than 10 days old?

At the moment I tag all these messages with the following macro, and then I save
it to the appropriate mailbox.

macro index \eA "T ~d>30d<enter>"

The above macro works well, but it gets a little cumbersome if you have to do it
in 30+ mailboxes.

Thank You

Danny

ps: When does one use <enter> and when does one use <return>, or are they the 
same?
