===Possible Email Bounces From Normally Working Sites===
+
*  The CS IT Support staff is back in Malone Hall. Our group is working a hybrid schedule with some of us working remotely on certain days, while others of our team are on campus. 
 +
* We continue being available M-F, 8:30 to 5pm, but there may be certain times we might be online only.
 +
*  Therefore, please remember to email [mailto:support@cs.jhu.edu support@cs.jhu.edu] for assistance.
 +
*  Also, please have [https://support.cs.jhu.edu/wiki/Zoom Zoom] available on your device(s), so that we can arrange to contact you using that method, as an alternative to in-person communication.
 +
* For the time being, Steve DeBlasio, our accounts liaison, is providing a virtual version of his daily office hours for accounts, etc.  Email [mailto:support@cs.jhu.edu support@cs.jhu.edu] for details.

'''8/8/16'''  We have been receiving reports of ''email bounces from people/organizations that normally work without problems.''  We think we know what is happening.  We were informed today that one of our CS student accounts compromised and sending spam.  So, sometime recently, the email reputation servers out on the internet got reports of such and updated their databases indicating as such.  We have since secured the compromised account and stopped its spamming.  So, now, we have to wait until the reputation servers see that no more spam is coming from CS and then they will reset our standing with them.  It usually takes a couple of days.  Mail servers out there use a variety of reputation servers.  They don't all reflect the same position on reputation of a domain.  So, some mail servers allow the mail to go through normally, while others might use a specific (or group of?) email reputation server.  And, we are at their mercy for those reputation servers to change the reputation score.

This problem doesn't happen often.  But, when it does, it causes some

headaches.  We're looking into some techniques/processes to be able to

detect this kind of issue in the future.

Will update here once the reputation scores have returned to normal.
