We are currently experiencing a problem in our outgoing mail servers. We are working with our provider to resolve the problem.
*** Update 6:30 PM ***
Outgoing email is currently being routed though an alternative mail server, while we correct the problematic mail server.
*** Update 11:30 PM ***
The outgoing email server is now fully restored. Servicer provides explains the problem was due to a malfunctioning "transparent spam filter box" in their network.
