Users who were logged into webmail or IMAP at this time may need to log out and back in again. This is due to a small system change made in preparation for upcoming system upgrades.

EMail Server Failure – Incoming Internet Mail Rejected
Mail coming to the EMU email server from the Internet was rejected between 5:00pm and 6:40pm today (Wed, 9/17). We estimate this involved about 1,000 messages, many of which were likely spam. The senders of this mail should have received error messages.
Webmail problem
The Webmail system was intermitently unavailable between 2:00pm and 4:00pm because of DNS issues. The problem has been resolved and InfoSys is monitoring the systems for any signs of additional trouble.
IMAP Slowdown
IMAP logins, including WebMail, were slow around noon today. The precise reason for the slow-down is under investigation, and InfoSys is watching the server for any repeat occurances.
Reconfigure RAID on IMAP Mail Server
Reconfigured the RAID disk on the IMAP email server (ms.emu.edu) so that the WRITE CACHE is enabled.
Although it was hoped this would be a fairly simple change, the reality was that an image of the 8gb disk had to be made and the RAID was then completely rebuilt. The actual reconfiguration effort began about 10am and was completed about 6pm. However, as a backup strategy in preparation for this procedure, the IMAP mail services were shutdown before the nightly backup of the server at 2am.
We believe this should improve the I/O performance of the IMAP mail server.
8+ Hr Webmail Server Outage.
The webserver service on the webmail server died about 4:00am, Sunday, 2/16. Adam Nolley notified Jack about 11:30am. Jack contacted Ben Beachy at home who was then able to dial in to the system, diagnose the problem and fix it. Service was restored about 12:20pm. Cause of problem was a program that was installed during a build of the server. The program was not being used but it’s license expired and it did not shutdown gracefully. The program has now been removed totally from the server.
10 Hr Webmail Server Failure
Weekly restart of Webmail Apache server(webmail.emu.edu) failed due to new config file entry. Only the Webmail server affected. Mail services from ms.mail.emu were unaffected.
15 Min WebMail Outage
WebMail experienced an outage of about 15 minutes. Users could not login to WebMail. Other IMAP services were unaffected. Network Admin made some config changes to get it working again. No clear explanation for the failure.
1 HR WebMail Server Outage – New Server Installation
New webmail server installation. Webmail will be off-line during this time while a new server is put into service that provides web access to the EMU IMAP email server.
15 Minute Planned EMail Server Outage
