July 22, 10:30am - We notice the Zimbra service on one mailbox server was running with a high load so we restarted the service. Only a part of the users were affected, and the service should be back to normal shortly.
Update 2:00pm - This problem appears to be resolved.
July 16, 2014 10:30am - It appears that mail being sent to comcast.com from exchange.upenn.edu is being rejected because it is being identified as spam. We have submitted a request to remove exchange.upenn.edu from Comcast's blacklist and anticipate that the situation will be resolved later this morning. If your mail was rejected, please try to resend later today.
ISC Networking and Telecommunications Email Service - Administrative
ISC Networking and Telecommunications provides email service
for various departments and schools across the University.
Each department that has email accounts on the ISC Networking and Telecommunications server
must have at least one administrator and not more than five
administrators who can assume responsibility for
managing the email accounts using local tools developed by ISC
Networking and Telecommunications. Administrators should have
some familiarity with supported email clients and
at least a cursory understanding of University processes.
While the administrator is the first line of support for the email
user and should try to resolve the user's email problem,
an administrator can escalate any problem to ISC Networking and
Telecommunications staff by submitting a request for assistance from the ProDesk web site.
