IT solutions: Email attachment size limits, file-upload time

Have you ever wondered if you were the only person on campus with a particular computer problem? Got a quick technology question and don’t know who to call? Contact the IT Help Desk, 785-532-7722, e-mail helpdesk@k-state.edu.

Question:  I am trying to send an attachment to my email in Zimbra webmail. What is the limit on the file size?

IT Help Desk:  The limit for each email in K-State’s Zimbra system is 50MB (megabytes) including attachments.  That’s 51,200KB (kilobytes); 1 megabyte = 1,024 kilobytes.

Malicious e-mail attachments infect numerous K-State computers

On Monday afternoon (July 13), thousands of K-Staters received malicious e-mail messages with .zip attachments. DO NOT OPEN THE ATTACHMENTS IN THESE E-MAILS, nor click on any links in these messages. Opening the attachment will result in your computer becoming infected and then being used to try to infect other computers by sending the malicious e-mails to accounts both on and off campus.

The malicious e-mails have subjects like:

  • Your friend invited you to twitter!
  • You have received A Hallmark E-Card!
  • Shipping update for your Amazon.com order 254-78546325-658742
  • Jessica would like to be your friend on hi5!

and the attachments have names like:

  • Invitation Card.zip
  • Postcard.zip
  • Shipping documents.zip

Nearly 100 K-State computers became infected on Monday when people opened the malicious attachments. Continue reading “Malicious e-mail attachments infect numerous K-State computers”
