Yahoo in recent days disabled autoforwarding for Yahoo Mail -- and in at least one corporate client's case, it disabled the webmail deletion feature. The autoforwarding feature "is under development," reads a statement on the Yahoo site. "While we work to improve it, we've temporarily disabled the ability to turn on Mail Forwarding for new forwarding addresses." There has been speculation that Yahoo turned off the autoforwarding feature to stem the tide of users quitting Yahoo Mail.
