Exchange email delivery issue

June 25, 2009 by Lars Rohrbach

As announced previously to EECS/BWRC Exchange users, the BWRC IronPort anti-spam appliance was scheduled to be moved to the campus datacenter this morning, with downtime expected between 6 am and 7 am.

Kevin Zimmerman has run into some problems getting the IronPort properly installed in the new location, and is working with the vendor to seek immediate resolution. Failing a quick fix, the IronPort appliance will be returned to its previous location, to restore Exchange email delivery service.

The BWRC IronPort generally handles all incoming EECS Exchange email, filtering out lots of spam. For the interim, I have updated forwarding for FONTUS Exchange users, so that new email as of 8:16 should go directly to FONTUS. This will allow normal mail delivery for FONTUS users, but will likely result in a temporary increase in received spam.

No mail will be lost. Email sent during the downtime will be delayed. BWRC Exchange users will continue to have mail delayed until the IronPort is back in service.

Thank you for your patience.

UPDATE

[2009-06-25 13:51:31 | Lars Rohrbach]

Kevin was successful in getting the IronPort configured for the new datacenter location, so it is again processing both incoming and outgoing Exchange email.

FONTUS users once again have their email also routed through the IronPort, to filter additional spam.

We apologize for the delay, and for any increased volume of received spam, during these technical difficulties.
