Forwarding Plusnet email to another address.

[#1]

I would like to forward all email to my Plusnet account to a different webmail account, but, i cant find out how!
I can see the redirect setting, but this is asking for a new email address, that will then get forwarded to my alternative.
I have several clients that contact me via my current PN address so i dont want to have to give them a new email address to send to.
Thanks

The best way I can think of to work around that would be to rename the current mailbox to something new and then create the necessary re-direct using the previous email address.
Doing this /should/ retain any email currently in the mailbox too
Other than this, I'd have to suggest setting it up in a mail client and setting up a rule to forward it to the new address if you still want to keep the emails in the plusnet mailbox too.
I hope this helps.
