Email Forwarders in cPanel will stop working

Hello,

We have recently received alot of customers that has problems with email forwarders in cpanel.

Example:
1. I setup a forwarder on me@mydomain.com to my email with one isp provider me@yahoo.com.
2. When I send a email to me@mydomain.com from me@gmail.com it should be forwarded to me@yahoo.com.
3. As gmail.com is using SPF records and Yahoo is checking incoming email and refuse all emails that is not accepted/added in google's spf it will not be delivered.

me@gmail.com -> me@mydomain.com -> (stops because of spf) me@yahoo.com

We see this problem on more and more providers as they change their email server setups.

So, is there any solution on this?
