Archivemail uses the Date fields in the headers to find the date of
the email.
This can be a problem with spam quarantines, since many
spam come with forged headers.
This will not delete all the spam in the quarantine that came in after
x days.
It will delete mail x days after the Date header fields of the message.
(which can be in the future, in which case it may take years
before it is deleted)
I never noticed that before. Thanks for the heads up and the sample usage!
