There was a problem during the morning of Monday January 29, 2007
that resulted in some email bouncing between 07:18 and 07:54.

One of the EECS mail servers running anti-virus software failed to
properly restart the anti-virus software (01/29/2007 07:18:31)
after it downloaded an updated pattern file.

The email server in question is configured to by default report a
transient mail problem when the anti-virus software is unavailable.
We were able to reproduce the expected transient mail problem
in our testing.

For reasons that are not currently apparent, it appears the EECS
Barracuda anti-spam appliances started bouncing some email during
the 07:18 and 07:54 time period Monday January 29, 2007. We would
have expected the transient mail problem to cause the EECS Barracuda
anti-spam appliances to try to send the messages again after a short delay.

The email problem was fixed Monday January 29, 2007 07:54 am.

We hope that any senders of email to an @EECS.Berkeley.EDU address during
the relevant time period will check their bounces and send/resend an
email if appropriate.

If you sent any email to an @EECS.Berkeley.EDU address during
the relevant time period please check to see if it bounced.

We are sorry for the inconvenience.
