Mail blocked by many large providers

At some point in the last day and a half, a client of digital.forest had their home computer compromised by some sort of malware which then used their logon credentials on one of our mail servers to send a large amount of "spam". We have been able to stop the flow of spam, and assist the client in changing passwords, but the result of the brief outbreak is that one of our main mailservers has been "blacklisted" (that is blocked from sending mail) by many other providers. These providers include AOL, Comcast, Hotmail, Juno Roadrunner, Shaw, and Yahoo. We are working with these providers to have the blocks removed as soon as possible, though this process may require several days to resolve completely. Additionally, we have re-routed most of our outgoing mail to not use the server that was affected. We appreciate your patience while we sort this situation out.

In the meantime, there are things that you can to to mitigate the risk of these sorts of blocks. Namely do not configure your mail here at digital.forest to automatically forward to another provider. The mechanism of auto-forwarding re-writes the "envelope" of email in such a way to make the mail appear to originate at digital.forest. If your account here receives spam from outside, and it automatically forwards to your account at Yahoo or Comcast, to them it appears as if the spam came from us. Frequently the error is compounded further if you then use that provider's "report as spam" webmail feature. Finally, please maintain the security of your home and office computers, and the integrity of your passwords, as their compromise can have widespread implications.
