The ability to add remote destinations for e-mail instead of archiving on disk.
Currently the e-mail archive utility allows users to archive incomming and outgoing e-mail. Archived e-mail is stored on an imap account but there is no way to forward this e-mail to an external address.
We have had requests from customers to be able to forward e-mails to an external address (to an exchange server for example).
This feature is usefull when a client hasn't got have enough disk space on his hosting account to store outgoing e-mails for a long period. Forwarding to an external account would solve this issue.
