Yahoo Block To Be Removed

The following missive was received this morning from Yahoo. Yahoo has been blocking mail from Synfibers for more than two months now following abuse of one of our proxy servers by spammers. Unlike many other blacklists, Yahoo does not re-test open relays for at least 60 days, which is why the problem was not resolved before now:

Thank you for contacting Yahoo! Customer Care.

We have retested the IP address you submitted and it appears that the open proxy/relay situation with this IP has been resolved. We have now removed the block from our servers for this IP address and will begin accepting connections again within the next day or so.
