Email forwarding not working on latest ispcp stable

[Iscp]

The most common reason for not forwarding emails forwarded through your domain is due to the forwarding address being a web based email (e.g. Hotmail, Yahoo), and the junk mail filters used to prevent spam/bulk email from cluttering up your inbox.
If you believe emails are not getting forwarded from your domain name then please try checking the junk mail folder on the forwarding address. If the forwarded emails are ending up in your junk mail folder it may be necessary to adjust your junk mail filter so that in future it will recognise any email forwarded from your domain name.
Please note it will take upto 1hr for your forwarding to become active once you have configured it. For new registrations it can take upto 24hrs.
