relays.osirusoft.com is a DNS blacklist used for spam filtering. It's terribly broken right now, so that admin is notifying people of that fact any time mail bounces.

The actual problem is this like:

550 5.1.1 <accountname@domain.net>... User unknown

No &quot;accountname&quot; at their end. Check e-mail address.

Thanks for the enlightenment. However, why would I get this problem when replying to an email I received?
